The disadvantage of creating more words is wasting paper to thicken your dictionary; this will take you longer to learn proper English especially if you are an ESL student. Instead, English borrow words from other laguages is clever and fun. Fun!? I heard a story about an English man came to Australia saw a strange creature jumpping on two leds. He pointed to the creature and asked an oboriginal "what is the creature name?". The oboriginal answer him kindly "kangaroo". The English man then write new-borrowing word in to English dictionary. An Australia native animal, Kangaroo, English meaning. But what does "kangaroo" mean in oboriginal language? It means "I don't understand you".
