Excusably → It is formed from "ex-" (meaning out of or from) and "causa" (meaning cause or reason) combined with the suffix "-ably" (meaning in a manner that is). The word "excusably" means in a manner that can be excused or justified, indicating that there is a valid reason for an action.
Think of 'out of' ('ex-') a 'cause' ('causa') that justifies an action — that's why excusably means something can be justified.
