Morphology

fifteen = five (transparent) = five + teen

The word is a regular numeral formation meaning 'five plus ten'; learners recognise '-teen' as forming the numbers 13–19.

Etymology

Fifteen comes from an old English way of saying 'five-ten', meaning five plus ten. So think of fifteen as 'ten and five', which is why it is the number after fourteen.
