'expands' is the definition.
The answer and definition can be both related to change as well as being verbs in their -s form.

'touches gingerly after roughage' is the wordplay.
I cannot really see how this works, but
an anagram of 'touches' is 'chesout' which is located in the answer.
'roughage' could be 'bran' (bran is a kind of roughage) and 'bran' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
