Applico/applicare/applicavi or applicui/applicatum or applicitum - to attach, place close to, to put in to shore.
Verb of the first declension, although as may be seen it can also form its past tenses following the pattern of the third conjugation. Using third conjugation past tenses is standard in the Vulgate, and later Latin in general.
It is formed from the preposition ad (towards) and the verb plico (to fold or coil). Adplico is an alternative spelling.
The English word 'apply' is related.
The two instances in the New Testament both refer to the nautical use - putting into shore. In the Old Testament, it is used multiple times, and in the wider sense of bringing close.
