Eraser – la gomme
(Pronounced 'gum' or 'gom' depending on regional variations.)
To remember that Eraser is pronounced gum or gom (gomme) in French, use the following mnemonic:
She didn't have an eraser so used bubble gum (gomme) instead.
Gomme is feminine, so it's la gomme. Imagine a labrador erasing the scent of other dogs with an eraser.
