Toy teaches French also (5,3)
I believe the answer is:
train set
'toy' is the definition.
(I've seen this before)
'teaches french also' is the wordplay.
'teaches' becomes 'trains' (training is a kind of teaching).
'french also' becomes 'et' ('and' in French).
'trains'+'et'='TRAIN SET'
(Other definitions for train set that I've seen before include "little loco with this?" , "model railway" , "Strange treats in store for this model toy" , "Toy with rail track" , "A child might play with this" .)
