Morphology

killer = kill (semi-transparent) = kill + er

Derived from 'kill' + '-er' but used figuratively to mean 'extremely difficult or exhausting', so the connection is metaphorical rather than literal.

Etymology

A helpful way to remember the informal use of killer is to think of something so hard or exhausting it could 'kill' you, with kill + -er used as a strong image. So a 'killer' task is one that is very difficult or tiring.
