The present Maureen intended, we hear (6)
I believe the answer is:
moment
'the present' is the definition.
(moment is a kind of present)
'maureen intended we hear' is the wordplay.
'maureen' becomes 'mo' (I've seen this in other clues).
'intended' becomes 'meant' (meaning is a kind of intending).
'we hear' indicates a 'sounds like' (homophone) clue.
'meant' is a homophone of 'ment'.
'mo'+'ment'='MOMENT'
(Other definitions for moment that I've seen before include "Significance; minute" , "Brief period of time" , "tick" , "A very brief portion of time" , "An exact point of time" .)
