Morphology

hotspot = hot + spot (transparent) = hot + spot

The sense is a literal combination of 'hot' (high temperature) + 'spot' (place), so the meaning is directly derivable.

Etymology

Hotspot joins hot ('very warm' or 'full of heat') and spot ('place'), so it literally means a 'very hot place'. That's why scientists call an area with unusually strong heat or radiation a hotspot.
