tacaño
/taˈkaɲo/ · B2 · adj
stingy, miserly, cheap, tight-fisted, niggardly, mean, penny-pinching
🪙🔒 sounds like 'tack on yo' — stingy folks tack the coins down and won't let go
Say ta-KA-nyo: picture-free trick is to link it to 'tack' (a pin that fixes things in place). A tacaño keeps coins pinned in place, tacked down, and never lets them move out of the wallet.
