matt

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

'one man's name' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'the master' becomes 'ma'.
'race' becomes 'tt'.
'ma'+'tt'='MATT'

'for' acts as a link.

Can you help me to learn more?
