Output a little lower? (5)
I believe the answer is:
calve
'little lower?' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for calve that I've seen before include "Release baby animal" , "Produce a young cow" , "(Of a glacier) release a mass of ice" , "Give birth (of cow, elephant etc)" , "left in grotto" .)
