Changes notices to include a small point (6)
I believe the answer is:
adapts
'changes' is the definition.
(adapting is a kind of changing)
'notices to include a small point' is the wordplay.
'notices' becomes 'ads' (I've seen this before).
'to include' is an insertion indicator.
'small point' becomes 'pt'.
'a'+'pt'='apt'
'ads' going around 'apt' is 'ADAPTS'.
(Other definitions for adapts that I've seen before include "Changes to fit new circumstances" , "Modifies for a new use" , "Makes fit or tailors to another purpose" , "Fits" , "Converts to a different use" .)
