分支

• Pinyin: fēn zhī
• Hanzi breakdown: 分 = 八 + 刀 (divide); 支 = 十 + 又 (ten + hand — a branch, a supporting arm; to branch off)

Meaning

Branch; offshoot; subdivision. A secondary line or division that stems from a main entity — used for organisations, academic fields, family lineages, rivers, or programming.

Versatile term used across many domains: an organisational branch, a version control branch (代码分支), a tributary river (河流分支), a phylogenetic branch (进化分支), or a subdivision of knowledge (学科分支). Neutral in tone. Different from 分部 (a regional administrative division) in that 分支 emphasises derivation from a common source.

Examples

1. 认知神经科学是神经科学的重要分支，研究大脑与认知关系。 Cognitive neuroscience is an important branch of neuroscience that studies the brain-cognition relationship.
2. 大河进入平原后分成多条分支，形成扇形三角洲。 After entering the plain, the river splits into several branches, forming a fan-shaped delta.
3. 团队为每项新功能创建独立分支，以保持主分支稳定。 The team creates an independent branch for each new feature to keep the main branch stable.
