Why is there a san in 照れ屋さん?


照れ屋さん means "a shy person", but I don't understand why there's a さん. When I
googled it I saw the usage of さん was nearly universal, but Google didn't say
why.




What do you mean by "name is shy"? 照れ屋さん means "a shy person" as a whole.

屋 is a suffix with [various meanings](https://jisho.org/search/%E5%B1%8B), one
of which is "person who tends to do ～" or simply "-er". Examples:

  * 照れ屋: a shy person
  * 頑張り屋: a hard worker
  * 寂しがり屋: someone who gets lonely easily; someone who cannot stand alone
  * 気取り屋: a smug person
  * 分からず屋: a stubborn/hardheaded person

This -さん has little to do with the meaning, but it is making the ～屋 word sound
more friendly and/or prettier. Please see the links in the comment section.
(It's not usually used with derogatory words like 気取り屋.)
