Combined a line with another, no breaks (3-2-3)

'combined' is the definition.
(all-in-one means combined in one thing)

'a line with another no breaks' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'one' and 'one' is located in the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is present in the answer.
'no' could be 'n' (common abbreviation y/n) and 'n' is located in the answer.
The remaining letters 'ali' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
