Personally, I use ‘savings’ as a catch-all for any form of money you have no intention of spending frivolously. Be that in savings, stocks, or other forms of investment.
I’ve got a relative who saw anything beyond the 6 month mark as spending money. I don’t know what form his investments manifested in, but it clearly didn’t work as he’s in financial do-do, and it’s an unpleasant topic amongst the family.
