- I = Eu. (subject) - am learning = estou aprendendo (verbal phrasing, present continuous). - to speak Portuguese = a falar o português (object of the verb 'am learning'). - every day = todos os dia (adverbial locution)
Then: "I am learning to speak Portuguese every day." Eu estou aprendendo a falar o português todos os dia
Obs.: 'every day' is literary translated to 'cada dia'.In Portuguese it means that in a range of days each of this days you learn Portuguese. But we do not use in this way. So the translation of 'each day' changes to "all of the days".
every day = cada dia all of the days = todos os dias
