Time to take small teaspoonful for one kind of rash? (7)
I believe the answer is:
hotspur
'one kind of rash?' is the definition.
The definition suggests a singular noun which matches the answer.
'time to take small teaspoonful' is the wordplay.
'time' becomes 'hour' (unit of time).
'to take' means one lot of letters goes inside another (inserted letters are taken in).
'small teaspoonful' becomes 'tsp' (I can't justify this - if you can you should believe this answer much more).
'hour' placed around 'tsp' is 'HOTSPUR'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for hotspur that I've seen before include "Fiery type" , "violent man" , "Rebellious warrior" , "Nickname of Sir Henry Percy (Henry IV, Part one)" , "Tottenham ____ FC" .)
