Morphology

derate = rate (semi-transparent) = de + rate

The prefix 'de-' suggests reduction and 'rate' suggests assigning a rating, but the specific engineering sense of lowering rated operating capacity is somewhat specialized.

Etymology

The word derate comes from the prefix de- meaning 'reduce' and the word rate meaning 'an allowed level or amount'. So to derate equipment is to lower its allowed power or capacity to keep it safe.
