The following is a list of general ideas to help you memorize foreign vocabulary.

1. Make your own vocabulary list and sound the words in your mind as you write them. Copying the words helps your mind retain the spelling, and sounding them out as you write helps you remember the pronunciation.

2. Never write a noun without its corresponding article, either a definite article (le, la, l', or les) or an indefinite article (un, une, or des). If the word is plural, since les does not show the gender, put an (f.) or an (m.) following, and learn the word with the gender.
3. Flash cards are very helpful and you can carry them in your pocket, to check when you have a few minutes to spare. Three-by-five-inch cards, cut in half, are fine. You can write the French word with the gender marker on one side, and the English on the other. These half-size cards are just the right size for the present tense of irregular verbs as well, with the infinitive (aller) and the English ("to go") on one side and the conjugation with subjects and their verb forms on the other side.
Note: Each lesson that presents new vocabulary includes a vocabulary quiz that allows you to enter the French equivalent to each English word or phrase, then check your responses against the correct answers.
4. Two-column technique. As you proceed through the course, and you need to be memorizing more vocabulary at one time, it is a good idea to start your own "dictionary." Fold an exercise book page in half lengthwise, and label the first column Français and the second column Anglais (French comes first so it is the first thing you see). Copy your target vocabulary into the first column and do not go over the middle line. English goes in the second column. Then check your passive knowledge by covering the English to see if you can recognize the French. Once you have passive knowledge of the whole page, cover the French column and try for active knowledge, looking at the English to see if you can retrieve the French. Check each page on a weekly basis. Just a quick check of a few words will help your memory retrieve the whole page. A regular review is necessary to transfer your knowledge from your short-term (neurological) memory to your long-term (chemical) memory.
5. Three-column technique. Fold a blank sheet of paper into three equal columns. The first is for your target French vocabulary, copy it with correct spelling. Then, from memory, write the English equivalents in the second column (your passive knowledge), and check it. Once the English column is correct, fold the first column behind the page so you cannot see the French, and try to retrieve the French from the English (active knowledge). Check the third column against the first column, make your corrections in bright-colored pen, then transfer the words with errors to the first column of your next three-column page.

These are just a few ideas to help with the mechanics of memorizing. Once you acquire the habit, it becomes very easy indeed to memorize. Du courage!
