I'm beginning to enjoy getting dressed outside, it's alleged (7)
I believe the answer is:
claimed
'alleged' is the definition.
(I've seen this before)
'i'm beginning to enjoy getting dressed outside' is the wordplay.
'beginning to' suggests taking the first letters.
'getting' means one lot of letters go next to another.
'dressed' becomes 'clad' (to be clad in something is to be dressed in it).
'outside' means one lot of letters goes inside another.
The initial letter of 'enjoy' is 'e'.
'im'+'e'='ime'
'ime' inserted within 'clad' is 'CLAIMED'.
'it's' acts as a link.
(Other definitions for claimed that I've seen before include "Asserted one's right to" , "Asserted, contended" , "Asserted right to or interest in" , "Alleged" , "Called for" .)
