Going through Genki and Lesson 15 has brought up 2 grammar points I can't figure really out.It would help me a lot if I understand how those two sentences are build up and why they need those parts.
to itte :said takara I think I have to break it up as ta and kara. ta being casual for desu.. But i don't get why it would need the copula. so the question is what is "ta" doing there? The translation would be Michiko told me to invite you. (the quotation is たけしくんも誘って)
みちこさんのうちに行こうと思ってるんだけど、一緒にいかない 。 ikou= volitional casual form of iku to omoutte= plan on doing. thinking about、 Here i have thought of several things sort of thing the "ru" is an abbreviation of iru n is added as it is an explanation. (I see it as connected with the proposal that follows of isshouni ikanai. and I think iru no could have been used as well. da as the copula kedo : is making the connection with the suggestion that follows. 一緒にいかない the translation according to Genki. I am thinking of going to Michiko's home. Do you want to go?
But again I am really unsure what the da is doing there.
Thank you for your time.
