Morphology

quintile = quint (semi-transparent) = quint + ile

The noun is derived from 'quint-' (five) with the suffix '-ile' to indicate one of five groups; the structure is logical but depends on knowledge of the combining form.

Etymology

Quintile as a noun also comes from the root quint- meaning 'five', just like in quintet. A quintile is 'one of five equal groups', so in statistics it names each of those five parts.
