Morphology

aggressive = aggress (semi-transparent) = aggress + ive

The medical sense ('spreading quickly' or 'highly severe') is a metaphorical/specialized extension of 'tending to attack or advance', so the link to the base is clear but somewhat technical.

Etymology

Aggressive comes from Latin ad- 'to' and gress 'step', giving the image of 'moving forward'; in medicine this helps remember that an aggressive illness 'moves forward' quickly and gets worse fast.
