Flowing, liquefied (5)
I believe the answer is:
runny
I believe this clue is a double definition.
'flowing' is the first definition.
(synonyms)
'liquefied' is the second definition.
(I've seen this before)
(Other definitions for runny that I've seen before include "Inclined to be rather liquid" , "(Exuding) liquid" , "Inclined to liquefy, watery" , "Tending to flow" , "(Of liquid) thin" .)
