'possessing joints' is the definition.
I can't judge whether this definition defines the answer.

'a curate lit up' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'curate'+'lit'='curatelit'
'curatelit' with letters rearranged gives 'rticulate'.
'a'+'rticulate'='ARTICULATE'

Can you help me to learn more?
