Speak for opening of new spot (9)
I believe the answer is:
pronounce
'speak' is the definition.
(thesaurus)
'for opening of new spot' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'opening of' suggests taking the first letters.
'spot' becomes 'ounce' (both can mean a small quantity).
The first letter of 'new' is 'n'.
'pro'+'n'+'ounce'='PRONOUNCE'
(Other definitions for pronounce that I've seen before include "Make the sound of (word)" , "Articulate in a certain way" , "Enunciate" , "make a declaration" , "Articulate clearly" .)
