Problem with /var

[Maureen Thomas]

I am running Debian 12 fulled updated. I keep getting a message saying 
that my /var is almost full.  What can I safely delete to make more room 
for it.  It is an HP Desktop Mo1-F3xxx, 8gb ram, Realtec Audio, AMD 
Ryzen 5 5600G.  I also have a 2TB Seagate HD plugged in for backups.

Any help will be greatly appreciated.
