Expecting ruling following pressure (8)
I believe the answer is:
pregnant
'expecting ruling following pressure' is the definition.
'pregnant' can be an answer for 'expecting' (thesaurus). I am not certain of the 'ruling following pressure' bit.
'expecting ruling' is the wordplay.
'expecting' becomes 'p' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ruling' becomes 'regnant' ('regnant' can be a synonym of 'ruling').
'p'+'regnant'='PREGNANT'
Can you help me to learn more?
(Other definitions for pregnant that I've seen before include "full of implications" , "With child, enceinte" , "Expecting a child" , "Gravid" , "Expecting a baby" .)
