Only Noel can make it (4)

I believe the answer is:

lone

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

'only' is the definition.
(synonyms)

'noel can make it' is the wordplay.
'noel' can be anagrammed to 'LONE'.
However, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for lone that I've seen before include "Sole" , "Solitary or single" , "Companionless" , "Unaccompanied" , "He likes to operate by himself" .)
