Just starting remarkably nice pint after one (9)
I believe the answer is:
incipient
'just starting' is the definition.
(I've seen this before)
'remarkably nice pint after one' is the wordplay.
'remarkably' is an anagram indicator (I've seen this in other clues).
'after' is a charade indicator (letters next to each other).
'one' becomes 'i' (Roman numeral).
'nice'+'pint'='nicepint'
'nicepint' is an anagram of 'ncipient'.
'ncipient' put after 'i' is 'INCIPIENT'.
(Other definitions for incipient that I've seen before include "Developing" , "Beginning to develop" , "Beginning to exist, in an early stage" , "Starting to happen" , "Nascent" .)
