Like the ornament that has a function? (6,6)

'like the ornament that has a function?' is the definition.
I know nothing about this answer so I can't judge whether this works.

'like the ornament that has a function?' is the wordplay.
I cannot quite understand how this works, but
'like' could be 'y' (similar in meaning) and 'y' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'function?' could be 'use' (synonyms) and 'use' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
