Squeeze a measure of column at foot of page (5)
I believe the answer is:
pinch
'squeeze' is the definition.
(I know that squeeze can be written as pinch)
'a measure of column at foot of page' is the wordplay.
'a measure of column' becomes 'inch' (I am not sure about this - if you are sure you should believe this answer much more).
'at foot of' says to put letters next to each other (in a down clue, some letters go below others).
'page' becomes 'p'.
'inch' put after 'p' is 'PINCH'.
Can you help me to learn more?
(Other definitions for pinch that I've seen before include "Steal; small quantity" , "Economise - steal" , "appropriate" , "amount of salt?" , "Grip sharply; steal" .)
