A pity to remove top after clothing has been provided, however boring it may be (10)
I believe the answer is:
uniformity
'been provided however boring it may be' is the definition.
I can't judge whether this definition defines the answer.
'a pity to remove top after clothing' is the wordplay.
'to remove top' means to remove the first letter (I've seen 'removes top' mean this).
'after' says to put letters next to each other.
'clothing' becomes 'uniform' (uniform is a kind of clothing).
'pity' with its first letter removed is 'ity'.
'ity' put after 'uniform' is 'UNIFORMITY'.
'has' acts as a link.
Can you help me to learn more?
(Another definition for uniformity that I've seen is " absence of change".)
