Smothering means covering something completely so that it can't get any air. It can also mean to kill someone by covering their face so they can't breathe.
Smothering can feel scary or dangerous. It can also feel like too much love or attention.
Examples:
The pillow is smothering the toy.
She is smothering the fire with a blanket.
The mother is smothering the baby with kisses.
The cat is smothering me with its fur.
The blanket is smothering me!
Stop smothering the cake with so much frosting!
