Suffix

-or

1. Creates an agent noun, often from a verb, indicating a person or object (often machines or parts of them) that do the verb or part of speech with which they are formed.

   ‎survive + ‎-or → ‎survivor

   Synonyms: -er, (casual) -ster

   Hyponyms: -a, -ess, -ette, -rix

2. (electrical science) Appended to the names of members of classes of components, especially those that have an extensive property name of the same root suffixed with -ance

Usage notes

In Latin-derived words, English generally appends this suffix where Latin would do it—to the root of a perfect passive participle (i.e. past participle). For other words, English tends to use the suffix -er. Occasionally both are used (protester vs. protestor).

Latin

Pronunciation

• (Classical) IPA^(key): /or/, [ɔr]
• (Ecclesiastical) IPA^(key): /or/, [ɔr]

Etymology 1

From Proto-Italic *-ōs, from Proto-Indo-European *-ōs, for original *-oss, compound suffix from *(é)-os (athematic) (neuter s-stem) +‎ *-s (masculine nominative).

The ō from the nominative case was made common to all cases originally with non-ablauting o (the three exceptions were arbor, mulier and Cerēs). Afterwards nom.sg. -ōr > -or, by Latin sound laws. Thus paradoxically, as in other r-stems (soror, -tor), in the resulting paradigm the one form with a short stem vowel is the only form whose stem was etymologically long.

   Synonyms: -ēs, -us
