We, sir, contrive to be better informed (5)

I believe the answer is:

wiser

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

'be better informed' is the definition.
I can't tell whether this definition defines the answer.

'we sir contrive' is the wordplay.
'contrive' indicates anagramming the letters.
'we'+'sir'='wesir'
'wesir' is an anagram of 'WISER'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for wiser that I've seen before include "Comparatively intelligent" , "more enlightened" , "More sagacious" , "More shrewd" , "More knowing" .)

I've seen this clue in the Evening Standard.
