Introductory drink provided after weary old man turns up (8)
I believe the answer is:
aperitif
'introductory drink' is the definition.
'aperitif' can be an answer for 'drink' (aperitif is a kind of drink). I'm not certain of the 'introductory' bit.
'provided after weary old man turns up' is the wordplay.
'provided' becomes 'if'.
'after' means one lot of letters go next to another.
'weary' becomes 'tire' (I've seen this before).
'old man' becomes 'pa' (both can mean father).
'turns up' shows that the letters should be reversed in order.
'tire'+'pa'='tirepa'
'tirepa' written backwards gives 'aperit'.
'if' put after 'aperit' is 'APERITIF'.
Can you help me to learn more?
(Other definitions for aperitif that I've seen before include "Stimulant taken before meal" , "Pre-meal appetiser" , "An alcoholic drink before dinner, an appetiser" , "alcohol before meal" , "Preliminary drink" .)
