Is it up to an artist to wear one? (5)
I believe the answer is:
tiara
'is it up to an artist to wear one?' is the definition.
I can't tell whether this defines the answer.
'it up to an artist to wear one?' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'to an artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'to wear' indicates putting letters inside.
'one?' becomes 'a' (a thing is one thing).
'it' with letters rearranged gives 'ti'.
'ti'+'ra'='tira'
'tira' placed around 'a' is 'TIARA'.
Can you help me to learn more?
(Other definitions for tiara that I've seen before include "Woman's crescent-shaped ornamental headdress" , "Jewelled crescent-shaped headdress" , "Small crown" , "Ornamental head band" , "Half-crown?" .)
