Appetitive is formed from "appetere" (meaning to strive for or seek) and the suffix "-ive" (meaning having the nature of). The word describes a tendency or nature to seek or strive for something, particularly in terms of desires or appetites.
Think of 'seeking' ('appetere') something you desire — that's why appetitive means having a nature to seek or strive for desires.
