‘A’ layer gets raise, so it seems! (10)
I believe the answer is:
apparently
'so it seems' is the definition.
(I've seen this before)
'a layer gets raise' is the wordplay.
'layer' becomes 'ply' (ply is a kind of layer).
'gets' is an insertion indicator (gets can mean captures or absorbs).
'raise' becomes 'parent' (synonyms).
'ply' going around 'parent' is 'pparently'.
'a'+'pparently'='APPARENTLY'
(Other definitions for apparently that I've seen before include "Clearly" , "so it seems" , "Seemingly" , "On the face of it" .)
