Is vast, perhaps, in certain views (6)

I believe the answer is:

vistas

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

'certain views' is the definition.
'vistas' can be an answer for 'views' ('vista' can be a synonym of 'view'). I am not certain of the 'certain' bit.

'is vast perhaps in' is the wordplay.
'perhaps' indicates anagramming the letters.
'in' is an insertion indicator.
'vast' anagrammed gives 'vtas'.
'is' inserted into 'vtas' is 'VISTAS'.

Can you help me to learn more?

(Another definition for vistas that I've seen is " Aspects, panoramas".)
