【BP0067】knuckle

knuckle

 

When you make a fist, your fingers bend and some bony bumps stick out. Those bumps are your knuckles!Knuckles are like tiny joints that make your fingers strong and flexible.

 

 

Example

  1. Knock knock! Rap your knuckles on the door.
  2. I stubbed my knuckle on the table.
  3. We need a bigger ring - it won't fit over her knuckle.
