Ladies going nuts, perhaps, on April 1st (5)
I believe the answer is:
aunts
'ladies going nuts perhaps on april 1st' is the definition.
I can't tell whether this defines the answer.
'nuts perhaps on april 1st' is the wordplay.
'perhaps' indicates an anagram.
'on' indicates putting letters inside (as in clothing \'on\' a person).
'april ast' becomes 'a' (first letter of the word 'April').
'nuts' with letters rearranged gives 'unts'.
'unts' placed around 'a' is 'AUNTS'.
Can you help me to learn more?
(Other definitions for aunts that I've seen before include "Relatives get bad US tan" , "Female relatives, usually older" , "relatively speaking" , "Sally and others" , "Parents' sisters" .)
