Give large coordinate soon (9)
I believe the answer is:
presently
'soon' is the definition.
(I know that soon can be written as presently)
'give large coordinate' is the wordplay.
'give' becomes 'present' (synonyms).
'large' becomes 'L' (eg in clothes sizes).
'coordinate' becomes 'Y' (as in X and Y coordinates on a grid).
'present'+'l'+'y'='PRESENTLY'
(Other definitions for presently that I've seen before include "In the near future" , "At the moment" , "Soon, in a little while" , "Before long" .)
