nixon

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

'president' is the definition.
(Richard Nixon)

I cannot understand how the rest of the clue works.

(Other definitions for nixon that I've seen before include "Ex-US president" , "US president, d.1994" , "Richard -, US president who resigned in nineteen seventy four" , "US president before Gerald Ford" , "Only US president to have resigned from office" .)

I've seen this clue in The Telegraph.
