Thank you both so much for the function.
One more question: what if I need to extract 2nd right most word? Just realized, I need to do this for some conditions. Is there a quick way to extract 2nd right most word?

"Administration Main Boston Office" = "Boston"

Thank you.

regexp_substr('Administration Main Boston Office','([^ ]+) *[^ ]+$',1,1,null,1)

or, if your version doesn't support substr back references


regexp_substr(regexp_substr('Administration Main Boston Office','[^ ]+ *[^ ]+$'),'[^ ]+')

another interesting variation for 2nd last word

reverse(regexp_substr(reverse('Administration Main Boston Office'),'[^ ]+',1,2))
