1: ναυαγέω
(Strong's #3489 — Verb — nauageo — now-ag-eh'-o )

signifies (a) literally, "to suffer shipwreck" (naus, "a ship," agnumi, "to break"), 2—Corinthians 11:25; (b) metaphorically, "to make shipwreck," 1—Timothy 1:19 , "concerning the faith," as the result of thrusting away a good conscience (both verbs in this ver. are in the aorist tense, signifying the definiteness of the acts).
