Crossword Genius

Pine used in making a tea chest (4)

Ross

I believe the answer is:

ache

'pine' is the definition.
(synonyms)

'in making a tea chest' is the wordplay.
'in' says the answer is hidden in the clue.
'ACHE' is hidden in the letters of 'making tea chest'.

'used' acts as a link.

(Other definitions for ache that I've seen before include "Play up" , "Cause pain" , "Dull throbbing pain" , "Hurt; yearn" , "anguish" .)

I've seen this clue in The Guardian and The Globe and Mail.
