It may conceal an evil manoeuvre (4)

I believe the answer is:

veil

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

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

'evil manoeuvre' is the wordplay.
'manoeuvre' indicates anagramming the letters.
'evil' is an anagram of 'VEIL'.

'an' acts as a link.

Can you help me to learn more?

(Other definitions for veil that I've seen before include "Curtain, disguise" , "Conceal, screen" , "Mantle" , "Transparent face cover" , "Covering for head and face" .)

I've seen this clue in the Evening Standard.
