Briefly refer to chaps with container containing oxygen (7)
I believe the answer is:
mention
'briefly refer' is the definition.
'mention' can be an answer for 'refer' (thesaurus). I'm not sure about the 'briefly' bit.
'chaps with container containing oxygen' is the wordplay.
'chaps' becomes 'men' (chap means a man).
'with' says to put letters next to each other.
'container' becomes 'tin' (tin is a kind of container).
'containing' indicates putting letters inside.
'oxygen' becomes 'O' (O is the chemical symbol for oxygen).
'tin' enclosing 'o' is 'tion'.
'men'+'tion'='MENTION'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for mention that I've seen before include "Passing reference" , "Make reference to" , "Speak of - refer to" , "state" , "Briefly refer to (something)" .)
