An expression, almost facetious, similar to "I offer you my emotional support" i.e. in lieu on money!
I ask for money to start a business and some say, "we'll give you our ____ support" in a funny way. Drawing a blank on this old, familiar expression! Like "you have my emotional, or thoughtful or something support" ???
Moral support
If you give someone moral support, you encourage that person and show that you approve of what they are doing, rather than giving practical help.
