Finishing or bringing to an end; making whole or entire by adding what is lacking.
From Latin 'complere' meaning to fill up completely, composed of 'com-' (together) and 'plere' (to fill). The word has maintained its core meaning of making something whole or finished.
The Latin root 'plere' meaning to fill gave us 'plenty', 'replete', and 'supplement' - all dealing with fullness or filling. To complete something is literally to fill it up entirely, leaving no empty spaces or missing pieces.
