Morphology

trisomic = trisome (semi-transparent) = tri + som + ic

The suffix 'ic' indicates an adjective form, but understanding requires knowledge of 'trisome'.

Etymology

Trisomic comes from the Greek parts tri- 'three' and soma 'body', the same tri- you see in triangle and the soma in chromosome. So trisomic describes a cell that has three 'bodies' (three copies) of one chromosome instead of the usual two.
