decathlete

The word 'decathlete' is a modern English formation, created by combining the Greek numerical prefix 'deca-' (meaning 'ten') with the noun 'athlete'. The term directly and logically describes a participant in the decathlon, an athletic contest consisting of ten separate track and field events. The prefix 'deca-' has a long history, deriving from the Greek 'deka', which itself can be traced back to the Proto-Indo-European root dekm̥, a fundamental term for the number ten. The word 'athlete' originates from the Greek 'athlētēs', meaning 'competitor in the games', from 'athlon' (prize, contest). Thus, the etymology transparently builds the meaning from its constituent parts: a 'ten-athlete' or 'competitor in the ten-event contest'.

Structure: deca (ten) + athlete (athlete) - deca: From Greek, a combining form meaning 'ten'. - athlete: From Greek, a combining form meaning 'contestant' or 'one who competes for a prize'.
