Hello, today when I was learning grammar, the ています verb form was introduced to me, the book however just explained the formal verb endings (e.g. 食べています), but didn`t cover the informal verb endings. The example conversation however had verbs, which I assume are the informal ones, so i wanna ask if my thoughts on how to conjugate the informal ones are correct:
One of the the examples was なにをしてるの (what are you doing?), so the same question but in formal would be なにをしていますか, if i`m not wrong.
So I assume that you just have to add the informal verb ending instead of the います. Do you do the same if you want to conjugate the past? So would it be なにをしてたの or なにをしてなかったの?
And what about regular verbs like はらう? How do you conjuate those, since はらってう doesn`t sound very correct to me xD
Im currently using Japanese From Zero 3 and i`m so far pretty happy with it. Will this topic maybe be covered in an other lesson?
