The grime developed around a secluded abode (9)

I believe the answer is:

hermitage

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

'secluded abode' is the definition.
'hermitage' can be an answer for 'abode' (hermitage is a kind of abode). I am unsure of the 'secluded' bit.

'the grime developed around a' is the wordplay.
'developed' is an anagram indicator.
'around' indicates putting letters inside.
'the'+'grime'='thegrime'
'thegrime' is an anagram of 'hermitge'.
'hermitge' enclosing 'a' is 'HERMITAGE'.

Can you help me to learn more?
