Anticipate moment with visitors? There's no time! (6-5)
I believe the answer is:
second-guess
'anticipate' is the definition.
'moment with visitors? there's no time' is the subsidiary indication.
'moment' becomes 'second' (second moment is a kind of moment**).
'with' says to put letters next to each other.
'visitors?' becomes 'guests' (guest is a kind of visitor).
'there's no' is a deletion indicator.
'time' becomes 't'.
'guests' with 't' taken out is 'guess'.
'second'+'guess'='secondguess'
(Other definitions for second-guess that I've seen before include "Anticipate (someone's action)" , "Attempt to anticipate or predict" .)
