Adit → It is formed from "ad-" (meaning to) and "ire" (meaning to go). The word "adit" refers to a passage or entrance, particularly one that leads to a place, as it signifies the act of going towards something.
Think of 'going to' ('ad-') a specific place ('ire') — that's why an adit is an entrance or passage leading to somewhere.
