kanji you can’t search on dictionary?

1 letter means something.
if 3 kanji combines, it would be something different.

Like "Now" , "Day" = Today

Strangely many times, I search kanji and there is no meaning. (Not always but very often.)
I tried 3 kanji letters. Copied to find the meaning.

I tried only 1 of the first and second and third. Then even tried 1st and 2nd, 2nd and third combined.
There was no meaning.

For example there is a kanji "Sun" "Moon" "Shine"
I can't read it so copied all 3. No meaning found.
Tried copying only 1 each time, and 2 each time.

Are you sure that the 3 kanjis you searched are actually one word?
It's kind of a very general question. There will be times where a "combination " of 3 kanjis is actually two words, sometimes it will be only one word, it might also be a place name or person name. Plus it all depends on the quality of the dictionary you use. You cannot expect in any language to find all possible words in a dictionary.

awesome site uriboy, thank you very much for the link.

@ rolandex
今日 is a correct combination.
https://en.wiktionary.org/wiki/%E4%BB%8A

But, second one can not understand what meaningful words you tried to make.
https://ja.wiktionary.org/wiki/sun
https://ja.wiktionary.org/wiki/moon
https://ja.wiktionary.org/wiki/shine

There are many words that Japanese people do not know "why that kanji are used?",
so it is important to know the meaning of each kanji,
but if you read it correctly, you will be able to find out the meaning yourself.

If you can read Japanese so so,
you should try to search on "Google" input "(a word) 語源(or 意味)"
https://en.wiktionary.org/wiki/%E8%AA%9E%E6%BA%90
(Don't input chinese kanji "语源")
https://en.wiktionary.org/wiki/%E6%84%8F%E5%91%B3

This is sample of unusual combination kanji(word) and reading harder if even a pure Japanese.

(2nd one is called "難読漢字 : nandoku kanji", for proper names, "katakana" is substituted cases a lot.)

@ Kenshiro
Only the automatic translation site is not perfect.
Only a word correct answer rate is high, but sentence cases are not.
How do you determine that the result is correct or not?

Every kanji has a meaning (or multiple meanings).

But you cannot just randomly combine multiple kanji to make a word (or expect it to mean something).

The only instance someone would make a "new word" by combining various kanji is when naming something (or someone). For example, if you are creating a character for a story. If you do that, you then have to decide how to read that new word. Because one kanji can be read many ways (on-yomi & kun-yomi & others).

Thanks.

I usually use jisho.com to find kanji.
There were 3 kanji words.
At first I did search the 3 kanji words that were stick together.
Then I didn't get a result. So I've tried separating and searching 1 by 1 or the first 2 and last 2 kanjis.
But I still couldn't get any result. Sometimes I do get a result if I do this separately however won't appear if I did all 3 that was stick together.

I do not know Xedni, but my last Kanji translator could not even Translate Gyokuro into Kanji, and weblio not only does it but tells me its a refined tea. I really liked that fact soo much, but you are right, obviously i cannot tell if its correct or not.

Why didn't you do?
