How do you stop new words from just slipping away?

Hey everyone! I’ve been super fired up about my studies lately, but I feel like I’m hitting a wall where new vocab just won't stick. I’m tired of that feeling when you learn a word one day and it’s gone the next! Right now I’m using basic flashcards, but do you have any wild or creative memorization hacks? I want to try something new to keep my progress moving. What actually works for you guys?
