Worker is shy about a humble dwelling (6)
I believe the answer is:
shanty
'a humble dwelling' is the definition.
'shanty' can be an answer for 'dwelling' (I have seen 'Ramshackle dwelling' mean 'shanty' so perhaps 'dwelling' could also mean 'shanty'). I'm not certain of the 'a humble' bit.
'worker is shy about' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'about' indicates putting letters inside.
'ant' inserted into 'shy' is 'SHANTY'.
Can you help me to learn more?
(Other definitions for shanty that I've seen before include "A sailor's sea song, or a rundown hut" , "Sea song - hovel" , "Poor home - sailors' song" , "Sailor's work song - ramshackle hut" , "Roughly built hut" .)
