Repeat, repeat and repeat. There are websites where you can fill in the words and it will ask you for the translation, till you know every word correctly. At the end you will get a note and you can see which words you did wrong the most.

When I am trying to memorize objects I put a sticky note on the object in my house with the translation on it

repeat and use it when you get the chance. think in the language you are learning , you can also speak to yourself :)

Thanks Hadeel

I think you should look up the word in dictionary then write it with it's definition and try to use it in sentences :)
