It suggests it may be undone in error (8)

I believe the answer is:

innuendo

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

'it suggests it may' is the definition.
The definition suggests a singular noun which matches the answer.

'undone in error' is the wordplay.
'error' indicates anagramming the letters.
'undone'+'in'='undonein'
'undonein' is an anagram of 'INNUENDO'.

'be' acts as a link.

Can you help me to learn more?

(Other definitions for innuendo that I've seen before include "Indirect reference to something rude" , "Oblique allusion" , "Implied smut" , "nudge nudge)" , "Aspersion" .)

I've seen this clue in The Globe and Mail.
