From Late Latin Titanicus, or its etymon Ancient Greek Τιτανικός (Titanikós, “of or relating to the Titans”), from Τιτᾶνες (Titânes, “Titans”) + -ικός (-ikós, “suffix meaning ‘of or pertaining to’ forming adjectives”). Τιτᾶνες (Titânes) is the nominative or vocative plural of Τῑτᾱ́ν (Tītā́n, “a Titan”), and then possibly: from τῐ́σῐς (tĭ́sĭs, “payment; atonement, penalty, punishment, retribution, reward; vengeance”), ultimately from Proto-Indo-European kʷey- (“to pay; to avenge”); or from τιταίνω (titaínō, “to extend, stretch”), from τείνω (teínō, “to extend, stretch; to spread; to exert, push to the limit, strain”), ultimately from Proto-Indo-European ten- (“to extend, stretch”); or * from τίτο (títo, “sun; day”), originally borrowed from Anatolian. The English word is analyzable as Titan + -ic (suffix meaning ‘of or pertaining to’ forming adjectives from nouns).
The proper noun is derived from Titanic (etymology 1, adjective senses 1 and 2.1), as the ship was the largest and thought to be the strongest in the world at the time it was constructed. The common noun is derived from the name of the ship.
Typically used as an attributive adjective before the noun it modifies.
