I have some rudimentary knowledge of japanese from previous attempts of trying to get familiar with the language. However, it is interesting to get to know it better and deepen some understanding.
For example, I had previously seen the Kanji 来 before as part of the word 来年 ( らいねん, “rainen”) which means “next year”. Today I learned that the character alone means “to come”, “to arrive” or “to approach”, which makes logical sense when the other character in that word means “year”, i.e. its literally “the coming year”. However, in a different context as a verb it is pronounce usually as くる (“kuru”) or simply き (“ki”).
Edit: Something else I just noticed: Duolingo rather soon teaches you the kanji for となり (“tonari”) which means “neighbor” or next to. It is 隣. That is of course a rather complicated Kanji, and I made a quick check on things I knew the word from already, such as My Neighbor Totoro (or となりのトトロ) and most of them simply use the hiragana as they are targeted at a younger audience.
