I'm a little stuck... Click here to teach me more about this clue!

'needing careful handling e' is the definition.
I can't tell whether this defines the answer.

'g frail in construction' is the wordplay.
'in' indicates putting letters inside.
'construction' becomes 'e' (I can't explain this - if you can you should give a lot more credence to this answer).
'g' put inside 'frail' is 'fragil'.
'fragil'+'e'='FRAGILE'

Can you help me to learn more?
