Yearn for brooch of emerald, first (4)
I believe the answer is:
pine
'yearn' is the definition.
(synonyms)
'brooch of emerald first' is the wordplay.
I cannot quite understand how this works, but
'brooch' could be 'pin' (decorative item pinned to clothing) and 'pin' is present in the answer.
'emerald first' could be 'e' (1st letter of 'emerald') and 'e' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for pine that I've seen before include "Tree, waste away" , "Long - tree" , "Evergreen conifer" , "Mope; tree" , "Fir tree; languish" .)
