Put in a low position, an apprentice needs help (4)
I believe the answer is:
laid
'put in a low position' is the definition.
'laid' can be an answer for 'put' (I've seen this before). I'm not certain of the 'in a low position' bit.
'an apprentice needs help' is the wordplay.
'an apprentice' becomes 'L' (as in a learner driver with L-plates on their car).
'needs' is a charade indicator (letters next to each other).
'help' becomes 'aid' (synonyms).
'l'+'aid'='LAID'
Can you help me to learn more?
(Other definitions for laid that I've seen before include "Placed horizontally on a surface" , "Wagered" , "Deposited" , "Doze" , "Put down like dial" .)
