She boards with silly old Roger or gets kicked out (6)

I believe the answer is:

lodger

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

'she boards' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'silly old roger or gets kicked out' is the wordplay.
'silly' indicates anagramming the letters.
'gets kicked out' is a deletion indicator.
'roger' with 'or' taken out is 'ger'.
'old' is an anagram of 'lod'.
'lod'+'ger'='LODGER'

'with' is the link.

Can you help me to learn more?

(Other definitions for lodger that I've seen before include "One who lives in a hired room" , "Renter of rooms" , "One renting a room in a house" , "One paying for accommodation" , "Boarder" .)
