A second-hand article. I don't care what (3,3,5)

'i don't care what' is the definition.
I can't judge whether this defines the answer.

'a second-hand article' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
'second' could be 'd' and 'd' is present in the answer.
'hand' could be 'l' (abbreviation for left, as in the left-hand side) and 'l' is found in the answer.
'article' could be 'thing' (both can mean an object) and 'thing' is found within the answer.
The remaining letters 'yo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
