Involve in late alterations (6)
I believe the answer is:
entail
'involve in late alterations' is the definition.
'entail' can be an answer for 'involve' (entail means to involve or require). I'm not sure about the 'in late alterations' bit.
'involve in late' is the wordplay.
'involve' indicates an anagram.
'in'+'late'='inlate'
'inlate' is an anagram of 'ENTAIL'.
Can you help me to learn more?
(Other definitions for entail that I've seen before include "Late in (anag.)" , "settle estates for the long term" , "Invlove or necessitate" , "Bring on an inevitable consequence" , "Inalienable estate" .)
