家庭 (jiā tíng) literally combines 家 (jiā), meaning 'home' or 'household', and 庭 (tíng), meaning 'courtyard' or 'yard'. Together, they form a formal, standard term for 'family'—referring to a group of people related by blood, marriage, or adoption who live together or share close emotional and social bonds. Unlike the more colloquial word 家 (jiā) alone—which can mean both 'home' and 'family' depending on context—家庭 emphasizes the social unit itself, often in written, official, or descriptive contexts.

This word is commonly used in discussions about family structure, responsibilities, education, health, and social policy—for example, in phrases like 家庭作业 (jiātíng zuòyè, 'homework'), 家庭医生 (jiātíng yīshēng, 'family doctor'), or 家庭关系 (jiātíng guānxi, 'family relationships'). It rarely refers to pets or non-human groups, and it carries no inherent connotation of size, wealth, or tradition—it simply denotes the core social unit.
