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

'italian merchant's' is the definition.
'antonio' can be an answer for 'merchant's' (I've seen this before). I'm not certain of the 'italian' bit.

'donation wanting day off' is the wordplay.
'wanting' suggests deleting specific letters (to want something can mean to lack it or need it).
'day' becomes 'd' (abbreviation for day).
'off' indicates anagramming the letters.
'donation' with 'd' removed is 'onation'.
'onation' is an anagram of 'ANTONIO'.

Can you help me to learn more?
