The word "evincive" is derived from the verb "evince", which is in turn derived from the Latin term "evincere". "Evince" entered the English language in the 17th century, borrowed from the Latin word "evincere", meaning "to conquer" or "to prove". The prefix "e-" in Latin implies "out", while "vincere" means "to conquer". Over time, "evincive" has evolved to describe something that is capable of demonstrating, proving, or eliciting a strong response. The addition of "more" in "more evincive" simply indicates a comparitive degree, emphasizing its stronger or more pronounced characteristic.
