Hesitation after that woman's rank (5)
I believe the answer is:
sheer
'rank' is the definition.
(as in sheer hypocrisy, rank hypocrisy etc)
'hesitation after that woman's' is the wordplay.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'after' says to put letters next to each other.
'that woman' becomes 'she' (she refers to a woman).
'er' put after 'she' is 'SHEER'.
(Other definitions for sheer that I've seen before include "avoid an unpleasant thing" , "Very thin and fine" , "needing to change a course" , "total" , "Very steep; utter" .)
