Oddly, love wearing quaint little number (6)
I believe the answer is:
twelve
'little number' is the definition.
'twelve' can be an answer for 'number' (I've seen this before). I am not sure about the 'little' bit.
'oddly love wearing quaint' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'wearing' means one lot of letters goes inside another.
'quaint' becomes 'twee' (both can mean sentimental or old-fashioned).
The alternate letters of 'love' are 'lv'.
'lv' placed into 'twee' is 'TWELVE'.
Can you help me to learn more?
(Other definitions for twelve that I've seen before include "Highest number on clock" , "Last hour" , "Number of zodiac signs" , "Midday" , "six couples" .)
