-i

For Semitic-speaking places, from the Arabic nisba suffix ـِيّ (-iyy) or from Hebrew ־י (-i), both sharing a common Semitic root.
For Indo-Iranian-speaking places, from Persian (-ī) and Hindi -ई (-ī).

In English, productive from the 19th century.

References

Etymology 2

From Latin -ī (nominative plural).

Pronunciation

enPR: ī, IPA^(key): /aɪ/ (traditional English)
enPR: ē, IPA^(key): /iː/ (rare; imitation of the original Latin or of Italian)

Suffix

-i

Forms an alternative plural ending for various words borrowed from Latin that end in ⟨us⟩ in the singular.
‎focus + ‎-i → ‎foci

‎radius + ‎-i → ‎radii

Usage notes

Prescriptively speaking, the ending is only applicable to words that were second-declension masculine nouns in Latin, such as the above examples. Descriptively speaking, the ending is often extended to other words like octopus (a third-declension noun in Latin with plural octopodes, not *octopi) and ignoramus (a verb in Latin, not a noun).
The ending traditionally “softens” preceding /k ɡ/ to /s d͡ʒ/, but non-softened pronunciations are also found today. Cf. loci /ˈləʊsaɪ/~/ˈləʊkaɪ/ and fungi /ˈfʌnd͡ʒaɪ/~/ˈfʌŋɡaɪ/.

Etymology 2

Conflated:

Etymology 1

From (especially Alemannic) Middle High German -ī, from Old High German -īn, from Proto-West Germanic *-īn (diminutive suffix). Generalized in Modern German through pet names like Rudi (Middle High German Ruodī). Cognate with English -en as in chicken, maiden.

Not directly related with English -ie, -y (from Old English -iġ), nor with Dutch -ie, -je (from Proto-West Germanic *-ikīn, whence German -chen). However, the vowel /i/ has an onomatopoeic quality to it, which is likely to reinforce its development or preservation in diminutives.

Suffix

-i (informal)

Forms pet names from given names, kinship terms, and terms of address.
‎Hans + ‎-i → ‎Hansi

‎Papa (“dad, daddy”) + ‎-i → ‎Papi (“pops”)

‎Schatz (“sweetheart, darling”) + ‎-i → ‎Schatzi
(endearing, sometimes derogatory) Forms nouns from adjectives and verbs denoting someone characterized by that word.
‎schlaff (“slack; weary”) + ‎-i → ‎Schlaffi (“weak, tired person”) (derogatory)

‎brummen (“to hum”) + ‎-i → ‎Brummi (“rig, truck”)
Forms clippings.
‎Pullover + ‎-i → ‎Pulli

‎Schokolade + ‎-i → ‎Schoki

Etymology 2

From various sources, chiefly Hebrew ־י (-ī), Arabic ي (-iyy), Persian (-ī), and Hindi -ई (-ī).

Suffix

-i (v-v^?, truncative^?)

Intransitivizes.

Usage notes

Sometimes additive after r stems.

Many verbs are intransitivized simply by changing the inflectional ending, without changing the stem; of those that do use an affix, it is not predictable which of -i, -nnig, -ller and -si are used. Also, verbs may use more than one of these, with similarly unpredictable results (e.g. errorsivoq (“wash clothes”) vs. erruivoq (“do dishes”), both from errorpaa). If a verb uses one of these affixes, the unaffixed intransitive form may be passive, reciprocal or reflexive w.r.t. the transitive form.

Synonyms

-nnig, -ller, -si

Etymology 1

Adjective-forming suffix.

Suffix

-i

(adjective-forming suffix) Added to proper nouns, certain common nouns and postpositions to form adjectives:
2. names of places (toponyms)
  ‎Amerika (“America”) + ‎-i → ‎amerikai (“American”)
4. names of people (anthroponyms, thus eponyms)
  ‎Freud (“Freud”) + ‎-i → ‎freudi (“Freudian”)
5. certain common nouns
  ‎város (“city”) + ‎-i → ‎városi (“urban”)
  
  ‎kémia (“chemistry”) + ‎-i → ‎kémiai (“chemical”)
6. postpositions (as part of the phrase in which they occur)
  ‎az ablak alatt (“under the window”) + ‎-i → ‎az ablak alatti szék (“the chair under the window”)

Usage notes

Final -o and -ö (which only occur in non-Hungarian words) change to -ó and -ő.^[1]
Oslo → oslói (“Oslovian”)

Malmö → malmői (“Malmö-based”)

Victor Hugo → Victor Hugó-i (“Hugolian, Hugonian, Hugoesque”)
If the suffix -i were to follow word-final -i, only one is retained (so one needs to know the original form).^[2]^[3]
Helsinki → helsinki (“Helsinkian”)

Zamárdi (a town in Somogy County, Hungary) → zamárdi (“from Zamárdi”, in theory, it could also derive from a non-existent *Zamárd)
The other word-final short vowels (a, e, u, ü) remain unchanged (just like long ones and consonants).
Prága (“Prague”) → prágai (“Praguian”)

Goethe → goethei (“Goethean”)

Peru → perui (“Peruvian”)

Öskü (a village in Veszprém County, Hungary) → ösküi (“from Öskü”)

The fact that word-final a and e remain short before the adjective-forming -i often becomes distinctive against the multiple-possession possessives of words that end in a and e, e.g. formai (“formal”) and formái (“his/her/its forms”) or megyei (“county-level”) and megyéi (“his/her/its counties”).

Names with a fleeting vowel: Eger → egri, as well as names ending in -halom, e.g. Szigethalom → szigethalmi.
Names ending in -falu (e.g. Leányfalu) may be suffixed in three ways: The official way is retaining the full form, e.g. leányfalui; in the vernacular, leányfalusi may be heard; and forms like leányfalvi are increasingly rare.^[4]
Names ending in a possessive suffix such as -falva, -halma, -háza, -földe (outside elements of proper names: földje), -telke: Official usage increasingly prefers retaining the whole name (e.g. nyíregyházai from Nyíregyháza), though in common parlance the word-final a and e tend to be dropped (e.g. nyíregyházi). The drawback of the latter is that the original form cannot be established (as nyíregyházi could theoretically derive from a non-existent *Nyíregyház).^[4]
For non–proper noun elements with a possessive suffix, native speakers often have a hard time trying to add this suffix, e.g. whether the last element of (Erzsébet királyné) útja and (Örs vezér) tere should become úti and téri (losing the mark of the possessive) or útjai and terei (having an ambiguous sense, primarily used for multiple possessions). As a rule of thumb, the former solution may be preferable.^[4]

  kapu (“gate”) → a kapui (“his/her/its gates”), az ő kapui (“his/her gates”)
  
  érme (“coin”) → az érméi (“his/her/its coins”), az ő érméi (“his/her coins”)
2. (with no noun for possessor, formal) your ……-s (second-person singular, grammatically resembling the third person sg.)
  kapu (“gate”) → a kapui (“your [formal] gates”), az ön kapui, a maga kapui (“your [formal] gates”)
3. construed with a noun or certain pronouns as the possessor: ……’s ……-s, ……-s of …… (third-person sg. or pl., depending on the noun or pronoun)
  az ember(nek a) kapui ― the person’s gates
  
  a gyerek(nek az) érméi ― the child’s coins

Usage notes

(possessive suffix) Variants:
-i is added to words ending in a vowel except -i. Final -a changes to -á-; final -e changes to -é-. The latter feature distinguishes it from the -i (adjective-forming suffix), which does not lengthen the preceding -a/-e.

-ai is added to some back-vowel words ending in a consonant

-ei is added to some front-vowel words ending in a consonant

-jai is added to some back-vowel words ending in a consonant or the vowel -i

-jei is added to some front-vowel words ending in a consonant or the vowel -i
- If the possessed noun is in the plural and the possessor is expressed in English with a possessive pronoun only (rather than a noun), e.g. “their toys” (as opposed to “the children’s toys”), the -ik/-aik/-eik/-jaik/-jeik suffixes are required in Hungarian.

Etymology 3

Personal suffix.

Suffix

-i

(personal suffix) Forms the definite third-person singular present tense of verbs (indicative mood).

Icelandic

Etymology

Etymology

Borrowed from Italian -i, Russian -и (-i). Also from English -i, used with Latin and Italian borrowings.

Pronunciation

IPA^(key): /i/

Suffix

-i

-s; marks the plural form of nouns, by replacing the -o ending
‎libro (“book”) + ‎-i → ‎libri (“books”)

Indonesian

Pronunciation

IPA^(key): [-i]

Etymology 1

Inherited from Malay -i, from Proto-Malayo-Polynesian *-i (local transitive suffix)

Suffix

-i (non-active/imperative/basic -i, active meng- -i, passive di- -i)

verbal suffix for manipulating, completing, or placing the object from a noun
transitive verbal suffix for causation in surface of the object from an adjective
transitive verbal suffix for doing activity to the object from a transitive verb
transitive locative imperative verbal suffix from a noun:
1. to apply or give [base] to the object
  Hormati orang tua! ― honour/respect parent!
2. to remove [base] from the object
  kuliti ― (de)skin, peel
transitive adverbial imperative verbal suffix from a noun: to act as/be [base] with reference to object
Sutradarai film ini! ― Direct this movie! (literally, “Become the producer of this film!”)

Usage notes

This suffix is never used after verbs ending in final -i for euphonic reasons and to avoid near-homophony with bare forms (-∅). Thus, beli (“to buy”) does not derive into *belii, although -in allows violation of the previous rule such as beliin (“buy it!”). Other examples include cari (← *carii) and capai (← *capaii).
When this suffix is combined with the prefixes meng-, di-, ter-, and ke-, the imperative aspect is lost.

Etymology 2

From Malay -i, from Arabic nisba suffix ـِيّ (-iyy).

Suffix

-i

adjective suffix (with the meaning “related to ...”)

Alternative forms

Etymology 3

There are two competing theories:

Formed analogically by borrowing the -i plural of Italian nouns in -o.

Suffix

-i (non-lemma form of noun-forming suffix)

used to form the plural of nouns ending in -e

Etymology 4

Perhaps from the Latin genitive singular ending -ī of masculine nouns in -us.

Etymology 1

Inherited from Proto-Malayo-Polynesian *-i (local transitive suffix).

Suffix

-i (Jawi spelling ـي, active meng- -i, 3rd person passive di- -i)

Gives a causitive meaning or a meaning of causing something to form imperative transitive verbs.
‎hamba (“slave”) + ‎-i → ‎hambai (“enslave”)

‎baik (“good”) + ‎-i → ‎baiki (“to make something good; to fix”)
Gives a locative meaning, that is, of stating a locational element to imperative verbs.
‎tumpah (“to fall out”) + ‎-i → ‎tumpahi (“fall onto”)

‎dekat (“close, near”) + ‎-i → ‎dekati (“get closer or nearer to; to approach”)

Usage notes

This suffix is never used after verbs ending in final -i for euphonic reasons and to avoid near-homophony with bare forms (-∅). Thus, beli (“to buy”) does not derive into *belii.

Suffix

-i

Forms adjectives indicating an abundance of something.
‎geađgi (“stone”) + ‎-i → ‎geađgái (“stony”)

‎vuodja (“fat”) + ‎-i → ‎vuddjii (“rich in fat”)

Usage notes

This suffix triggers the strongest grade on a preceding stressed syllable.

Phonologically, the suffix is actually the consonant j, and so it forms a diphthong with the final vowel of the base word's stem rather than replacing that vowel. Thus, the resulting word is essentially identical to the illative singular form. The noun declines as a contracted stem, with the inflectional stem lacking the -i.

Pronunciation

IPA^(key): /i/

Suffix

-i

A suffix forming infinitives of many verbs.

Usage notes

Most verbs with infinitives in -i are marked by the once-inchoative infix -esc- in many parts of their conjugation, as well as in various derived words; two such verbs are vorbi (“to say”) and iubi (“to love”).
A sizable group of verbs have infinitives in -i but do not use the infix -esc-, and are otherwise fairly regular; these include, among others, the common verb dormi (“sleep”), simți (“feel”), auzi (“hear”).
There is a variant form, -î, derived from the same Latin source.

New Tribes	-i

Etymology 1

Unknown; unlike the other possessive suffixes found in the language, -i has no known cognates in any other Cariban language.

Pronunciation

IPA^(key): [-i]

Suffix

-i

marks a noun as possessed; used mostly with nouns referring to instruments, technologies, and manufactured products, and also with all loanwords

Etymology 2

Alternative forms

-∅ (allophone after diphthongal i)

Pronunciation

IPA^(key): [-i]

Suffix

-i

forms the singular of the recent past perfective tense
forms the singular of the distant past perfective tense when both the agent and patient (if there is one) of the verb are third-person

Usage notes

This suffix does not cause syllable reduction. When it attaches to a stem that ends in a vowel followed by i, this suffix is unrealized (disappears).

The second sense can be readily distinguished from the first because it requires the distant-past third-person marker kün- instead of ordinary person markers.

Derived terms

-icho

Etymology 3

Possibly of the same origin as the previous suffix.

Pronunciation

IPA^(key): [-i]

Suffix

-i

forms the prohibitive mood

Usage notes

When the patient/object of a verb with this suffix is third-person, or when the object/patient is first-person and the subject/agent is second-person, it must also take the prefix ön- (or one of its allomorphs) after the person marker. However, this prefix is not found when the object/patient is first-person and the subject/agent is third-person.

Etymology 4

Pronunciation

IPA^(key): [-i]

Suffix

-i

forms the interrogative of the third-person form na of the copula ei
