Is forced to leave the tea unfinished and to hurry (5)
I believe the answer is:
haste
'to hurry' is the definition.
(synonyms)
'is forced to leave the tea unfinished' is the wordplay.
'is forced to leave' becomes 'has' (I can't explain this - if you can you should give a lot more credence to this answer).
'unfinished' means to remove the last letter.
'tea' with its final letter removed is 'te'.
'has'+'te'='HASTE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for haste that I've seen before include "dispatch" , "''Marry in . . . . ., repent at leisure''" , "Expedition" , "Rapidity" , "Inconsiderate speed" .)
