In every way or as much as possible; to the fullest extent; entirely and thoroughly.
Formed from 'complete' plus '-ly', with 'complete' coming from Latin 'completus', past participle of 'complere' meaning 'to fill up, finish'. The Latin combines 'com-' (intensive prefix) with 'plere' (to fill), literally meaning 'filled up entirely'.
What makes 'completely' fascinating is its perfect symmetry with its opposite 'incompletely' - yet we use 'completely' far more often in daily speech. This reflects a human tendency to think in terms of totality and finality, making 'completely' a cornerstone word for expressing the absolute nature of actions or states.
