In a way that shows a lack of courage or determination; timidly or cowardly.
He pusillanimously avoided confrontation, choosing to stay silent instead.
Pusillanimously → It is formed from "pusillus" (meaning small or weak) and "animus" (meaning spirit or mind) with the suffix "-ly" (meaning in a manner). The word describes acting in a manner that is small-minded or lacking courage.
Think of someone acting in a 'small' or 'weak' way ('pusillus') with a 'weak spirit' ('animus') — that's why pusillanimously means acting timidly or cowardly.
