Nice head of lettuce held by worker on the land (8)
I believe the answer is:
pleasant
'nice' is the definition.
(associated in meaning)
'head of lettuce held by worker on the land' is the wordplay.
'head of' says to take the initial letters.
'held by' means one lot of letters goes inside another.
'worker' becomes 'ant' (worker is a type of ant).
'on' says to put letters next to each other.
'the land' becomes 'peas' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'lettuce' is 'l'.
'ant' after 'peas' is 'peasant'.
'l' inserted into 'peasant' is 'PLEASANT'.
Can you help me to learn more?
(Other definitions for pleasant that I've seen before include "Charming" , "Enjoyable, agreeable" , "Affable, good-humoured" , "Likeable, friendly" , "sweet?" .)
