Right before this vocab, I learned the Kun’yomi reading of the vocab 上 which was うえ and now in this vocab, even though the Reading Explanation says it’s Kun’yomi as well, it sounds completely different
あげる。Can someone explain what’s going on? LIke a word can have multiple Kun’yomi reading as well?
It helps to remember that Japanese writing evolved from Chinese writing.
At the risk of making a gross oversimplification, if two things were written using the same way in classical Chinese, there’s a decent chance that they’ll be written using the same character in Japanese, too, even if spoken Japanese makes a clear distinction. Similarly, some words have different kanji because Chinese makes a distinction between them, even though they are essentially the same word in Japanese.
For example, in Chinese, 上 can mean both “up” and “ascend” (along with a bunch of other things), which is likely why it is used both for うえ and あがる (and, by extension, あげる).
As ObolioJ suggests, it’s probably best not to think of it as remembering a bunch of readings, but rather as recognizing different words. After all, when you see the words tough, though, thought, through and thorough, you probably don’t think too much about how the individual letters are pronounced; with enough experience, your mind learns to recognize the word as a whole, allowing you to identify the entire word as a whole (especially when you see it as part of a sentence where only one of the five options makes sense).
Not precisely your question, but kanji can also have a third type of reading called “nanori”, which is a reading that’s only ever used in names. The nanori for 上 are あおい, あげ, い, か, かき, かず, かん, こう, のぼり and ほつ.
don’t stress yourself trying to learn these. You’ll literally only ever need to know them when you meet someone who has one of these readings in their names, so you can just learn that specific reading at such a hypothetical future moment.
I’m currently sitting at level 7 in the WaniKani spectrum and it can be daunting, but the vocab helps. Just keep pace with your lessons and reviews and (slowly) it all begins to click together. Good luck!
I want to echo that it’s easier to focus on remembering how to read words. Some kanji have a specific reading for a very specific word. Remembering all that just to say that you know the kanji would be a nightmare.
Your brain will pick up on the patterns and you will be able to guess the readings to words you haven’t seen before.
Yeah, there’s often kanji that you only see in one relatively common word/combination, like of the top of my head: 躊躇、揶揄、偸閑. I could never remember how to read those readings/kanji separately, but it’s easy to see as a word in context. Often they even have furigana, since some of the kanji can be a bit archaic.
Also, sometimes the same word can also be written with different kanji, 上げるand 挙げる both read as あげる. When different kanji are used sometimes the meaning is slightly different so I should not say the “same word” but perhaps words with similar meanings and identical readings…
