Lexical Definition

‎τρώγω‎ trṓgō (tro'-go) to eat ^G:V
probably strengthened from a collateral form of the base of ‎τραῦμα‎ and ‎τρίβος‎ through the idea of corrosion or wear

eat.

• or perhaps rather of a base of ‎τρυγών‎ and ‎τρίζω‎ through the idea of a craunching sound
• to gnaw or chew, i.e. (generally) to eat

Abbott-Smith

* τρώγω
1. prop., of animals, to gnaw, munch, crunch (Hom., al.).
2. Of men, to eat raw food, as vegetables, nuts, etc. (Hdt., al.).
3. In late vernacular, simply to eat (= ἐσθίω): Mt 24:38, Jo 6:54, 56, 57, 58 13:18 (LXX ἐσθίων) (v. Kennedy, Sources, 82, 155; MM, xxv).†
