Vegetables obtained by worker, a lowly labourer (7)
I believe the answer is:
peasant
'a lowly labourer' is the definition.
'peasant' can be an answer for 'labourer' (peasant is a kind of labourer). I'm not sure about the 'a lowly' bit.
'vegetables obtained by worker' is the wordplay.
'vegetables' becomes 'peas' (peas are a type of vegetable).
'obtained by' means one lot of letters go next to another.
'worker' becomes 'ant' (worker is a type of ant).
'peas'+'ant'='PEASANT'
Can you help me to learn more?
(Other definitions for peasant that I've seen before include "Rural person of low class" , "Poor farmworker" , "Poor rustic" , "Poor country worker" , "Rural labourer" .)
