Morphology

decile = deci- (semi-transparent) = deci + ile

Built from the combining form 'deci-' meaning 'ten' plus the nominal/derivational '-ile'; the numeric combining form is technical and not a common standalone word, so the relation is only partly clear to average learners.

Etymology

Decile comes from the Latin root dec- and decem meaning 'ten', the same root you see in decimal and decade. In statistics a decile is one of ten equal parts of a set of data, so the origin helps you remember it means a 'one-tenth' part.
