Denominative verbs are formed from the stems of nouns (substantives or adjectives). Verbs lacking such a noun-stem are made on the model of the ordinary denominative verb. The principal terminations are as follows:
1. -αω: derived chiefly from words with ᾱ stems (a few from words of the second declension). Verbs in -αω denote to do, to be , or to have, that which is expressed by the stem.
τῑμά-ω honour (τῑμή, stem τῑμᾱ-), ᾱ̓ριστά-ω breakfast (ᾱ̓́ριστο-ν breakfast), τολμά-ω dare (τόλμα daring, stem τολμᾱ-), κομά-ω wear long hair (κόμη hair). κοιμά-ω, lull to sleep, has no primitive noun.
On -ιαω and -αω denoting a desire or a bodily condition, see 868 b.
2. -εω: derived chiefly from όε- stems (834 f), and thence extended to all kinds of stems. Verbs in -εω denote a condition or an activity, and are often intransitive.
οἰκέ-ω dwell (οἶκο-ς house, οἰκόε-), φιλέ-ω love (φίλο-ς dear, φιλόε-), ὑπηρετέω serve (ὑπηρέτης servant, ὑπηρετᾱ-), εὐτυχ-έ-ω am fortunate (εὐτυχής fortunate, εὐτυχεσ-), μῑσ-έ-ω hate (μῖσος hate, μῑσεσ-), σωφρον-έ-ω am temperate (σώφρων), μαρτυρ-έ-ω bear witness (μάρτυς, -υρ-ος).
a. Some εω-verbs from εσ-stems have older forms in -είω (624 a).
3. -οω: chiefly derived from ο-stems. Verbs in -οω are usually factitive, denoting to cause or to make.
δηλό-ω manifest, make clear (δῆλο-ς), δουλό-ω enslave (δοῦλο-ς), ζηλό-ω emulate (ζῆλο-ς emulation), ζημιό-ω punish (ζημίᾱ damage), μαστῑγό-ω whip (μάστιξ, -ῑγος whip). ἀρόω plough has no primitive.
On the formation of the present stem of verbs in -αω, -εω, -οω, see 522.
4. -ευω: derived from substantives from ευ-stems (607) and thence extended to other stems. ευω-verbs usually denote a condition, sometimes an activity.
βασιλεύ-ω am king, rule (βασιλεύ-ς), βουλεύ-ω counsel (βουλή), κινδῡνεύ-ω venture, incur danger (κίνδῡνο-ς), παιδεύ-ω educate (παῖς boy, girl), θεραπεύ-ω attend (θεράπων attendant).
5. -ῡω (rare): from υ-stems, as δακρῡ́-ω weep (δάκρυ tear). Cp. 608.
6. -οζω, -ιζω: derived originally from stems in δ or γ (as ἐλπίζω hope = ἐλπιδ-ῖω, ἁρπάζω seize = ἁρπαγ-ιω), and thence widely extended to other stems (cp. 623 δ, γ). Such verbs denote action.
γυμνάζω exercise (γυμνάς, -άδ-ος stripped, naked); ἀναγκάζω compel (ἀνάγκη necessity); ἀτῑμάζω dishonour (ἄτῑμος); βιάζομαι use force (βίᾱ force); θαυμάζω wonder (θαῦμα); φροντίζω take care (φροντίς); ὑβρίζω insult (ὕβρι-ς outrage); νομίζω consider (νόμο-ς custom, law); τειχίζω fortify (τεῖχ-ος wall, stem τειχεσ-); χαρίζομαι do a favour (χάρις, -ιτος favour).
a. Verbs in -ιζω and -ιαζω derived from proper names express an adoption of language, manners, opinions, or politics:
ἑλληνίζω speak Greek (Ἕλλην), βακχιάζω act like a bacchante (βακχιάς), λακωνίζω imitate Laconian manners (Λάκων), μηδίζω side with the Medes (Μῆδος).
b. Verbs in -εζω, -οζω, and -υζω are rare (πιέζω press, poet. δεσπόζω am lord, κοκκύζω cry cuckoo).
7. -αινω: originally from stems in -αν + ι̯ω (518), but usually extended to other stems. See 620, III.
μελαίνω blacken (μέλᾱς black, μελαν-), εὐφραίνω gladden (εὔφρων glad, εὐφρον-), σημαίνω signify (σῆμα, σήματ-ος sign), χαλεπαίνω am angry (χαλεπό-ς hard, angry).
8. -ῡνω: from stems in υν + ῖω (519). The primitive words often show stems in υ. See 620, III.
βαθῡ́νω deepen (βαθύ-ς deep), ταχῡ́νω hasten (ταχύ-ς swift), αἰσχῡ́νω disgrace (αἶσχ-ος shame), θαρρῡ́νω encourage (θάρρ-ος courage).
