make (something) stick
To cause something to be permanent, established, or able to persist. I've been trying to teach my class the equation all week, but nothing seems to make it stick. The district attorney is afraid we won't be able to make the charges stick if we arrest the suspect now.
Make effective or permanent, as in They tried to appeal but our lawyers made the verdict stick. This idiom uses stick in the sense of "adhere." [First half of 1900s]
