A different head of art — him, presumably? (7)

I believe the answer is:

another

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

'head of art him presumably?' is the definition.
The definition suggests a singular noun but the answer is not.

'a different' is the wordplay.
'a' becomes 'an'.
'different' becomes 'other' (similar in meaning).
'an'+'other'='ANOTHER'

Can you help me to learn more?

(Other definitions for another that I've seen before include "Someone else" , "No heart (anag.)" , "On earth (anag.)" , "Additional, one more" , "A different (thing)" .)

I've seen this clue in The Times.
