inertia

I'm a little stuck... Click here to teach me more about this clue!

'the lethargy' is the definition.
(both can mean a lack of movement)

'i retain however moved' is the wordplay.
'i retain' can be anagrammed to 'INERTIA'.
Though, I am not clear how this is indicated.

Can you help me to learn more?

(Other definitions for inertia that I've seen before include "'Sluggishness, indolence (7)'" , "Lethargy" , "I retain, being without energy" , "Slowness to act, lack of strength" , "showing reluctance to move" .)

I've seen this clue in The Globe and Mail.
