What is this form of grammar called?
Sets, I use the + "have" + "version participle of a verb" + + for a standing examples: I have played guitar for 3 years. I have written a diary since I was 12th It has for a while pottery. I also think this sentence Form is Genzai in-kei Japanese. Oh, it's actually genzai Kanryo Kei in Japan. I think this ruling also applies to only the verb form, but somehow, if we are teaching genzai Kanryo Kei, they do not teach how has them in like a completely different meaning: "I played the guitar!"
The verb is the present perfect.
