however, there are many exceptions to these patterns. for example, some native japanese words with two or more kanji (usually proper nouns) use their kanji's kun-yomi, like 山口, which is pronounced "yama-guchi", even though the on-yomi for the kanji would be "san" and "kō" in that order. sometimes, kanji only have on-yomi and have no kun-yomi. for example, the kanji 毒, which means "poison", only has the on-yomi "doku". sometimes, compound words mix on-yomi and kun-yomi together. for example, the word 金色, which means "golden", is pronounced "kin-iro", in which the first kanji uses its on-yomi, and the second-kanji uses its kun-yomi. sometimes, the kanji in certain compound words may not even use their kanji readings at all, but are used only to show the word's meaning. for example, the word 煙草 is pronounced "tabako", which means "tobacco" in english. this word was borrowed from portuguese, and while the pronunciation of the word does not match either kanji, the meaning of the kanji are "smoke" and "grass" in that order, hinting at the word's meaning. there are even some words whose kanji can be used to only show a word's pronunciation and not its meaning. these are called ateji. for example, the word 亜米利加, which means "america", is pronounced "amerika", but none of the kanji meanings have any obvious connection to america. usually, however, words of the last kind are usually written in only katakana these days, though sometimes words like "sushi" still written in ateji, like 寿司, because chinese tourists will recognize the ateji more easily, since the word is written the same way in chinese.
