The full name abbreviated (5)

I believe the answer is:

monty

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

'abbreviated' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'the full name' is the wordplay.
'the full' becomes 'mon' (I am not sure about this - if you are sure you should believe this answer much more).
'name' becomes 'Ty'.
'mon'+'ty'='MONTY'

Can you help me to learn more?

(Other definitions for monty that I've seen before include "The Full - - (film)" , "Nickname of World War II general" , "Diminutive for Montgomery" .)
