2. Coming home you get your dictionary and start looking for the word "wet"
Try to find anything about "wet" you might need in a normal day by day conversation: the adjective, adverb, the verb and phrases made up with "wet"

Write everything down in an organized way.
Don't choose, write words, compound words, phrases, expressions and verb-preposition combinations you probably will not use.
Just focus on necessary vocabulary, idiom.

3. In order to memorize the word more easily, play with it:

find synonyms: damp, drenched
find the antonym, the oppositi word: dry
find homonyms : wed
use in humorous, bizarre context: wet water
use in a context of your daily life: he still wets his bed

Don't simply try to learn the isolated word. Try to learn by using it in context. Use it in sentences.

4. Get your flashcard program and make a special about the word "Wet", using all the words and phrases you found in your dictionary.
Do not only put isolated words, to memorize, but also phrases containing "wet" and related words.
Adding pictures is a good idea for visual learner, while auditory learners might benefit from adding sound; the pronunciation of the words.

Don't overload your flashcard file: 20 cards per file should be enough: it's better to memorize in small portions than long extended lists.
It's much more important to train each small portion on a regular basis during a long period.
