One man's name for the master race (4)

I believe the answer is:

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 they can define each other.

'master race' is the wordplay.
'master' becomes 'ma' (Master of Arts).
'race' becomes 'tt'.
'ma'+'tt'='MATT'

'for the' acts as a link.

Can you help me to learn more?
