Not any point saving last of Belgian waffle (8)

I believe the answer is:

nonsense

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

'waffle' is the definition.
(thesaurus)

'not any point saving last of belgian' is the wordplay.
'not any' becomes 'no' (similar in meaning).
'point' becomes 'sense' (I can't explain this - if you can you should give a lot more credence to this answer).
'saving' indicates putting letters inside.
'last of' says to take the final letters.
The last letter of 'belgian' is 'n'.
'no'+'sense'='nosense'
'nosense' placed around 'n' is 'NONSENSE'.

Can you help me to learn more?
