The simple act of writing down a new word and its definition can help you remember it. Vocabulary word flash cards are pretty easy to make and serve you and anyone else interested in building their vocabulary — just use the following steps:
Buy a stack of 3-by-5 index cards.
Write new words on the front of a card (one word per card).
Write the definition, part of speech, and pronunciation on the back of the card.
Take your cards with you and study them.
