由此 (from this)

• 拼音: yóucǐ
• 结构: 由此 + Result Clause / 由此可见 + Conclusion
• 汉字拆解: 由 = 田 (field) with a vertical stroke (path through); 此 = 止 (stop) + 匕 (spoon/person)

含义

由此 (yóucǐ) means 'from this,' 'hence,' or 'as a result of this.' It connects a preceding fact or event to its logical consequence, implication, or conclusion.

由此 is a formal connective that links a cause, basis, or premise to the result or inference that follows. It is more literary than 因此 (therefore) and carries a stronger sense of logical derivation rather than simple causation. While 因此 emphasizes 'because of this,' 由此 emphasizes 'starting from this point' — the consequence grows organically out of the premise. It frequently appears in academic writing, news commentary, and formal speeches. 由此可见 (from this one can see) is a very common fixed phrase used to draw conclusions.

起源与历史

由此 combines 由 (from, by means of) and 此 (this). In Classical Chinese, 由 meant 'to follow a path from,' so 由此 literally means 'following from this point,' indicating logical progression from premise to conclusion.
