Can this sign be used for the word 'crush'?
Yes, this sign is often used interchangeably for words like 'crush,' 'grind,' or 'smash.' It is especially appropriate when referring to food preparation, like crushing garlic, or physically pressing something down against a surface. The context of your sentence will make the exact English translation clear.
Does it matter which hand does the mashing?
Yes, it does! In ASL, your dominant hand should always be the active hand performing the movement. Your non-dominant hand should serve as the stationary base. If you are right-handed, your right hand will do the twisting while your left hand remains flat and still.
How can I show that I am mashing something very hard?
ASL uses non-manual markers to show intensity. You can modify the sign by using a more forceful, deliberate twisting motion with your dominant hand. Pair this with an intense facial expression, such as furrowing your brows or pursing your lips, to visually demonstrate the physical effort.
