What should be taken if wise man turns up after party? (6)
I believe the answer is:
dosage
'what should be taken if wise' is the definition.
I can't tell whether this definition defines the answer.
'man turns up after party?' is the wordplay.
I cannot quite understand how this works, but
'man' could be 'sage' (I have seen 'Wise man' mean 'sage' so perhaps 'man' could also mean 'sage') and 'sage' is found in the answer.
'party?' could be 'do' (do can informally mean a party) and 'do' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dosage that I've seen before include "Medicine administered" , "Administered amount of drug" , "measure" , "Correct use of a prescribed drug" , "Quantity of medication" .)
