Supply air like a freebooter (8)

Ross

I believe the answer is:

aspirate

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

'supply air' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I can't see?

'like a freebooter' is the wordplay.
'like' becomes 'as'.
'a freebooter' becomes 'pirate' (pirate is a kind of freebooter).
'as'+'pirate'='ASPIRATE'

Can you help me to learn more?

(Other definitions for aspirate that I've seen before include "Breathe in; sound of h" , "First appearance of Hook" , "Hook, initially" , "Stop" , "Breathed consonant" .)
