您

您 (nín) is the polite second-person singular pronoun — the respectful version of 你 (nǐ, 'you'). Use 您 when addressing elders, teachers, customers, bosses, strangers in formal or service contexts, or anyone you want to show respect to. The character is built from 你 (you) on top and 心 (heart) on the bottom — 'you in my heart,' a respectful 'you.' Two tips for learners: first, the standard plural is 你们 (nǐmen, 'you all'), not 您们 — Mandarin generally treats the polite form as singular; for plural respect, use 各位 (gè wèi, 'everyone') or 大家 (dàjiā, 'everybody'). Second, the politeness is real and noticed — Beijing speakers in particular use 您 frequently, while southern speakers may use it less. The greeting 您好 (nín hǎo) is the polite upgrade of 你好.

Note: 您 is the polite/respectful form of 'you,' used to show deference to elders, customers, teachers, strangers in formal contexts, or anyone of higher status. Using 你 with someone who deserves 您 can sound rude; using 您 in a casual peer setting can sound stiff or distant.

Memory hook: 您 = 你 (you) + 心 (heart). Putting 'you' over 'heart' shows respect — this is a heartfelt 'you.'
