gostaria de saber.
quando se usa was ou were? E quando se coloca "to" antes do verbo?
Você vai usar was com as pessoas no singular, e were com as pessoas no plural, basicamente.
i was you were he was she was it was we were they were
Quanto ao "to" antes do verbo, você vai usar quando quiser utilizar os verbos no infinitivo. To Study (Estudar) To Play (Jogar, Tocar, etc...)
