Morphology

iffy = if (transparent) = if + y

The adjective is derived from 'if' + '-y' meaning 'full of ifs' (i.e., conditional/uncertain), so the meaning is directly recoverable.

Etymology

Iffy comes from the small word if plus the ending -y, so it literally means 'full of ifs' or 'maybe'. That's why something iffy is uncertain or not fully reliable.
