Mostly tough sort of steak - needs last drop of syrah to clear your throat (8)
I believe the answer is:
harrumph
'clear your throat' is the definition.
I can't judge whether this defines the answer.
'mostly tough sort of steak needs last drop of syrah' is the wordplay.
'mostly' means to remove the last letter (most but not all of the word).
'tough' becomes 'hard' (similar in meaning).
'sort of steak' becomes 'rump'.
'needs' says to put letters next to each other.
'last drop of' suggests the final letters.
The last letter of 'syrah' is 'h'.
'hard' with its last letter taken off is 'har'.
'har'+'rump'+'h'='HARRUMPH'
'to' is the link.
Can you help me to learn more?
(Other definitions for harrumph that I've seen before include "Express grumpy opposition" , "Clear one's throat noisily" , "Noise of throat clearing" , "Sound of someone clearing throat" , "Clearing of the throat - expression of dissatisfaction" .)
