How much is taken from slipshod sea dog? (6)
I believe the answer is:
dosage
'how much is taken' is the definition.
I can't judge whether this defines the answer.
'slipshod sea dog?' is the wordplay.
'slipshod' indicates an anagram.
'sea'+'dog'='seadog'
'seadog' is an anagram of 'DOSAGE'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for dosage that I've seen before include "The giving of medication in prescribed amount" , "Sea dog (anag)" , "quantity of drug" , "measure" , "Provision of medicine in prescribed amounts" .)
