write the words on little cards and whenever you have a break you can easily refer to them always try to find the word's simple meaning as well as its usage in examples for example : refreshed (meaning) Refresh one's memory, Make fresh again (usage) "The cool water refreshed us" use little cards which fits in your pockets
