Insignificant person to enforce delay upon being picked up (10)
I believe the answer is:
makeweight
'insignificant person' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for makeweight that I've seen before include "It helps the balance" , "Unimportant addition to complete something" , "deficiency" , "An unimportant extra" , "Filler" .)
