It’s to do with showing regard for others (10)
I believe the answer is:
respecting
'it's to do with' is the definition.
I can't judge whether this definition defines the answer.
'regard for others' is the wordplay.
'regard' becomes 'respect' ('respect' can be a synonym of 'regard').
'for' says to put letters next to each other.
'others' becomes 'ing' (I can't justify this - if you can you should believe this answer much more).
'respect'+'ing'='RESPECTING'
'showing' is the link.
Can you help me to learn more?
(Another definition for respecting that I've seen is " showing esteem".)
