I know the lyrics to that song by heart.

The project was aided by a generous donation.

The city's population is dominated by young professionals.

By definition, a square is a quadrilateral with four equal sides and four right angles.

By dint of hard work, she was able to achieve her goals.

By and by, the sun will set.

The by-election will be held next month.

The baby said bye byes before going to sleep.

Bye-bye!

The bystander watched the fight from a safe distance.
