Morphology

underactive = active (transparent) = under + active

The adjective is formed by productive prefixation 'under-' meaning 'insufficiently' added to the adjective 'active', so the meaning 'less active than normal' is directly derivable.

Etymology

Underactive combines under meaning 'below' and active meaning 'working' or 'moving', so it literally describes something that works below the usual level. That's why doctors use it for a gland or part of the body that is less active than normal.
