Is Esperanto going to get any harder, because right now it seems so easy.
Wouldn't "He and she are reading a letter" also be correct? I thought that present tense verbs could also act as the present progressive verbs. For example: "Li atendas nin" can be either "He waits for us" or "He is waiting for us".
It would stay the same There is no difference between "Mi legas" and "Ŝi legas"
