1.
using -san (honorific); addressing someone with -san
The practice of attaching the honorific suffix さん to a person's name when addressing or referring to them. Indicates a basic level of politeness and respect.
The word 付け means 'attaching' or 'affixing,' so さん付け literally means 'attaching さん.' This pattern is productive: ちゃん付け (using -chan), くん付け (using -kun), 様付け (using -sama) all follow the same structure. In many Japanese workplaces, there has been a trend toward さん付け as a way to create a more egalitarian atmosphere, replacing 役職呼び (addressing by job title).
