Air guest loses it in quarrels (6)
I believe the answer is:
argues
'quarrels' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe you can see a link between them that I don't see?
'air guest loses it' is the wordplay.
'loses' suggests deleting specific letters.
'air'+'guest'='airguest'
'airguest' with 'it' taken out is 'ARGUES'.
'in' is the link.
Can you help me to learn more?
(Other definitions for argues that I've seen before include "Disputes, expresses disagreement" , "Disputes, contends verbally" , "Quarrels or disagrees" , "Debates or bickers" , "Disputes, proposes the contrary" .)
