tellurian

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

'inhabitant of earth' is the definition.
'tellurian' can be an answer for 'earth' (thesaurus). I am unsure of the 'inhabitant of' bit.

'inform geller an' is the wordplay.
'inform' becomes 'tell' (telling is a kind of informing).
'geller' becomes 'uri' (I've seen this in another clue).
'tell'+'uri'+'an'='TELLURIAN'
