A slug on our ground is lethargic (10)

Ross

I believe the answer is:

languorous

'lethargic' is the definition.
(similar in meaning)

'a slug on our ground' is the wordplay.
'ground' indicates anagramming the letters ('grind' the letters into a new form).
'a'+'slug'+'on'+'our'='aslugonour'
'aslugonour' with letters rearranged gives 'LANGUOROUS'.

'is' is the link.

(Other definitions for languorous that I've seen before include "Full of dreamy inertia" , "Dreamy -- our UN goals (anag)" .)
