Sight the four of us recalled? (4)
I believe the answer is:
view
'sight' is the definition.
(I know that sight can be written as view)
'four of us recalled?' is the wordplay.
'four of us' becomes 'we IV' (IV is four in roman numerals).
'recalled?' says the letters should be written in reverse (I've seen 'recalling' mean this).
'weiv' back-to-front is 'VIEW'.
'the' acts as a link.
(Other definitions for view that I've seen before include "Sight - opinion" , "Opinion; inspect" , "See" , "Natural scenery or mental attitude" , "Range or field of vision" .)
