Sloth and one near it on the move (7)
I believe the answer is:
inertia
'sloth' is the definition.
(I've seen this before)
'one near it on the move' is the wordplay.
'one' becomes 'I' (Roman numeral).
'on the move' indicates an anagram.
'near'+'it'='nearit'
'nearit' anagrammed gives 'nertia'.
'i'+'nertia'='INERTIA'
'and' acts as a link.
(Other definitions for inertia that I've seen before include "showing reluctance to move" , "Lack of activity" , "Listlessness" , "Idleness" , "Sloth; inactivity" .)
