A growing source of second-class accommodation (5)

I believe the answer is:

broom

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

'a growing source' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'second-class accommodation' is the wordplay.
'second class' becomes 'b'.
'accommodation' becomes 'room' (I have seen 'basic accommodation' mean 'room' so perhaps 'accommodation' could also mean 'room').
'b'+'room'='BROOM'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for broom that I've seen before include "Yellow-flowered shrub" , "Yellow-flowering shrub" , "Long-handled brush" , "A new - - sweeps clean" , "Shrub and cleaning implement" .)
