Morphology

triploid = diploid (transparent) = tri + ploid

The prefix 'tri-' clearly indicates three, and 'ploid' relates to chromosome sets, building on the concept of 'diploid'.

Etymology

Triploid comes from the beginning tri- meaning 'three' (as in triangle) and the ending -ploid meaning 'fold' or 'set'. So triploid means 'three sets', which explains why it describes cells or organisms with three complete sets of chromosomes.
