title

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

'be nominal' is the definition.
I can't tell whether this definition defines the answer.

'let it' is the wordplay.
'let it' can be anagrammed to 'TITLE'.
Though, I am unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for title that I've seen before include "Name of book or lord" , "Distinctive name" , "Right of ownership" , "confers ownership" , "Appellation signifying status or function" .)

I've seen this clue in the Evening Standard.
