Duck drink with lass, ignoring idiot (4)

I believe the answer is:

teal

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

'duck' is the definition.
(teal is a kind of duck)

'drink with lass ignoring idiot' is the wordplay.
'drink with' becomes 'tea' (tea is a kind of drink. I am not sure about the 'with' bit.**).
'ignoring' is a deletion indicator.
'idiot' becomes 'ass' (I've seen this before).
'lass' with 'ass' taken away is 'l'.
'tea'+'l'='TEAL'

Can you help me to learn more?

(Other definitions for teal that I've seen before include "Species of duck" , "Small, short-necked duck" , "Small river duck" , "Variety of duck" , "Duck - dark greenish-blue" .)
