Imagine no end of malice against one guru (8)

I believe the answer is:

envisage

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

'imagine' is the definition.
(synonyms)

'no end of malice against one guru' is the wordplay.
'no end of malice' becomes 'en' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'against' becomes 'v' (abbreviation for 'versus').
'one' becomes 'i' (Roman numeral).
'guru' becomes 'sage' (synonyms).
'en'+'v'+'i'+'sage'='ENVISAGE'

Can you help me to learn more?

(Other definitions for envisage that I've seen before include "Picture in one's mind" , "Form a mental picture of (something)" , "Conceive of, imagine" , "See" , "Visualise, imagine" .)

I've seen this clue in The Times.
