Morphology

centile = cent (semi-transparent) = cent + ile

The relation to 'cent' ('hundred') is clear, but the specific statistical technical meaning 'one of 100 ranked divisions' is specialized and not automatically inferred by an average learner.

Etymology

Centile comes from the Latin root cent- (from centum) meaning 'one hundred'. Think of it like 'percent': a centile marks a point that divides a group into 100 equal parts, so the 75th centile means you are above about 75 out of 100 people.
