Is NOT listed as irregular..
When you say "Can someone help me to understand why this is?" you just want to know why the word isn't listed as "irregular"? Is that an established tag that appears on words with readings that are something other than plain on/kun? If you have examples, that might help me understand.
If you just want to know where the reading comes from, デジタル大辞泉 explains it like this:
「く」は「木」、「だ」は「の」の意
く is 木, だ has the meaning of の

I guess strictly speaking, that would make it a kind of jukujikun reading I guess?
It's not a question about why it's not listed as irregular, it's more about wanting to know where the reading that's used in the word came from. In my Kanji study, I use common words like this to help me remember a Kanji's readings. It would help if there was a way to quickly identify those words that do not use the common standard Kanji readings. This has been helpful, thank you.
Kanji reading for 果物
In the word for fruit, 果物 pronounced くだもの (kudamono), when I look at the first kanji in the word (果), くだ is not listed as either an ON reading or a KUN reading. The word is listed as irregular. Can someone help me to understand why this is?
