I received a form letter from the company.

I received a love letter from my secret admirer.

She felt lethargic after staying up all night.

The letter carrier delivers mail to our house every day.

The police successfully defused a letter bomb that was sent to the government office.

Her performance was letter-perfect.

The movie was a letdown.

The snake's venom is lethal.

I couldn't shake off the lethargy no matter how much I slept.

I love eating lettuce in my salads.
