Start removing lid (7)

Ross

I believe the answer is:

opening

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

'lid' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'start removing' is the wordplay.
'start' becomes 'open' (opening is a kind of starting).
'removing' becomes 'ing' (I can't explain this - if you can you should give a lot more credence to this answer).
'open'+'ing'='OPENING'

Can you help me to learn more?

(Other definitions for opening that I've seen before include "Inauguration" , "First -- beginning" , "Aperture or first night" , "Initial" , "break" .)

I've seen this clue in The Telegraph.
