Baldie almost moving freely (2-3)
I believe the answer is:
ad-lib
'freely' is the definition.
(short for ad libitum, 'at one's pleasure' in Latin)
'baldie almost moving' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'moving' indicates an anagram (letters are moved around).
'baldie' with its final letter taken away is 'baldi'.
'baldi' anagrammed gives 'AD-LIB'.
(Other definitions for ad-lib that I've seen before include "freely" , "Speak without preparation" , "Improvise" , "Off the cuff remark" , "Talk without notes" .)
