Why is the Kanji 「太」read 「ふとし]?


I found this one from a title of a manga
[チャンピオン太](https://ja.wikipedia.org/wiki/%E3%83%81%E3%83%A3%E3%83%B3%E3%83%94%E3%82%AA%E3%83%B3%E5%A4%AA)

As my understanding, it should be read just as「ふと」.




So-called i-adjectives in Modern Japanese used to end with _-shi_ in Classical
period. Some boy's names still retain those old forms, such as たかし, さとし, つよし,
やすし, ひろし or ふとし (conversely, they wouldn't name their boys in Modern adjective
forms like たかい, さとい, つよい etc).

There's one more thing that Japanese names often contain some "unordinary"
kun'yomi of kanji that might beyond your imagination. They also derives from
obsolete readings in olden times now mostly confined within personal or proper
names (名乗【なの】り). For example:

> たかし: 高, 喬, 崇, 貴, 隆, 尭, 敬, ...
