Meaning

A compound particle meaning 'under' in the figurative sense — under the control, guidance, supervision, or influence of someone or something. It conveys 'under the direction of' or 'within the framework of.'

の下で expresses that an action takes place under the authority, guidance, conditions, or influence of someone or something. It is used both for people (先生の下で = under the teacher's guidance) and for abstract conditions (厳しい規律の下で = under strict discipline). The particle で indicates the circumstance, while の下 specifies the hierarchical or conditional relationship. A variant の下に is also common and slightly more formal. This pattern carries a respectful or formal tone and is frequently seen in academic, professional, and historical contexts. It should not be confused with the literal spatial meaning of 下 (below/underneath a physical object).

Examples

1. 有名な教授の下で三年間研究を続けた。 I continued research for three years under a famous professor.
2. 厳しいルールの下で選手たちは練習している。 The athletes are practising under strict rules.
3. 新しいリーダーの下で会社は大きく変わった。 Under the new leader, the company changed dramatically.
