In a way that cannot be defeated or overcome; showing great strength or resilience.

Invincibly → It is formed from "in-" (meaning not) and "vincere" (meaning to conquer or overcome) and the suffix "-bly" (meaning in a manner). The word "invincibly" means in a manner that cannot be conquered or overcome.
Think of 'not' ('in-') being able to 'conquer' ('vincere') — that's why invincibly means something that cannot be defeated.
