"MY VOCAB PRACTICE."

1. Multiply.
   Rabbits and mice seem to multiply in great numbers if not kept under control.

2. Multitude.
   My mother used to tell me to "Wear big clothing, it hides a multitude of sins," while she was struggling to put on her girdle.

3. Multifaceted.
   A diamond, depending on cut, is multifaceted to give it sparkle and show off it's fire and brilliance.

4. Multilingual.
