  • (1st CE Egyptian) IPA(key): /tiˈkos/

  • SuffixEdit

    -τῐκός (-tikósm (feminine -τῐκή, neuter -τῐκόν); first/second declension

    1. Added to verbal stems to form adjectives: relating to, suited to, skilled in, able to, -ive
      ποιέω (poiéō, to make) + ‎-τικός (-tikós) → ‎ποιητικός (poiētikós, creative)
    2. Added to other stems to form adjectives, particularly those ending in vowels
      ἔξω (éxō, outside) + ‎-τικός (-tikós) → ‎ἐξωτικός (exōtikós, foreign)
      ναυ-ς (nau-s, ship) + ‎-τικός (-tikós) → ‎ναυτικός (nautikós, seafaring)

    Usage notesEdit

    Certain sound changes happen before the suffix, as before other derivational or inflectional suffixes beginning in τ (t). Labial stops β, π, φ (b, p, ph) become π (p), dental stops δ, θ, τ (d, th, t) become σ (s), velar stops γ, κ, χ (g, k, kh) become κ (k).

    Contracted verbs, which have stems ending in a vowel, use the long form of the vowel – this happens, for instance, in the example above: ποιέ (poié)ποιη-τικός (poiē-tikós).
