Root Breakdown

Root-derived
inter-between, among
+
estto be, to exist
=interest

inter- (between) + est (it is, from Latin esse) = 'it is between' — the Latin phrase inter est meant 'it makes a difference.' Something between you and an outcome concerns you, so you have a stake in it. From this come curiosity, financial stake, and loan interest alike.

Why It Means This

The many senses of interest all grow from one Latin idea: inter est, 'it is between' / 'it makes a difference.' What lies between you and an outcome is what you care about and have a stake in. That single notion split into curiosity (mental stake), financial interest (a stake in a business), and loan interest (the lender's stake in being repaid). Far from being unrelated meanings, they are siblings born of the same 'being between.'
