She, left aside with no answer, cracked - wanting the protector of her body (8)

'she left' is the definition.
The definition suggests a singular noun which matches the answer.

'aside with no answer cracked wanting the protector of her body' is the wordplay.
I cannot really see how this works, but
'wanting' could be 'less' (I've seen this before) and 'less' is located in the answer.
'her' could be 'de' and 'de' is found in the answer.
The remaining letters 'hi' 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?
