Still into recent infantile stuff (7)
I believe the answer is:
layette
'infantile stuff' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'still into recent' is the wordplay.
'still' becomes 'yet' (yet can mean still or so far).
'into' indicates putting letters inside.
'recent' becomes 'late' (similar in meaning).
'yet' placed within 'late' is 'LAYETTE'.
Can you help me to learn more?
(Other definitions for layette that I've seen before include "Complete set of clothing for a baby" , "baby things" , "small outfit" , "Kit for baby" , "Clothes and accessories for newborn child" .)
