Morphology
quintile = quint + ile
Built from the combining form 'quint-' (five) + suffix '-ile'; the numeric element is not a common standalone English word, so learners familiar with number-based patterns (quartile, decile) may infer the meaning, but many will not.
Etymology
Quintile comes from the old Latin root quint- meaning 'five', the same root in familiar words like quintet and quintuple. So when something is described as quintile, it relates to dividing things into five equal groups.
