In portugues, most verbs change the form... for exemple: In english we say "I like this" but in portugues, if you say it, is like to say "I to like this". So, in this situation, in portuguese, you need to say "EU ('I' subject) gostO ('like' flexed verb) disso('this'). we can not translate precisely because our language has many different rules. But, if you help me to learn english, i can help you to learn portuguese! Thank you!
