Mite with odd discharge (4)

I believe the answer is:

emit

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

'discharge' is the definition.
(emitting is a kind of discharging)

'mite with odd' is the wordplay.
'mite' anagrams to 'EMIT'.
Though, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for emit that I've seen before include "Give out or pour forth" , "Give out (eg light)" , "Broadcast" , "Produce and discharge" , "Let out" .)

I've seen this clue in The Mirror.
