Meaning
The kanji 制 (sei) is a versatile character conveying core concepts like "system," "control," "establish," and "restrict." Essentially, it implies an act of shaping, regulating, or bringing something into order. You'll frequently encounter it in words related to rules, structures, regulations, and the act of creating or enforcing them. Think of 制 as the fundamental element behind anything structured, managed, or held within boundaries, such as a 教育制度 (educational system) or 時間制限 (time limit).
Its etymological roots offer a compelling look into its meaning. The kanji 制 is composed of two main elements: on the left, a component (often related to 'fabric' or 'shaping'), and on the right, 刀 (dāo), meaning a knife or sword. The original form is believed to have depicted a person cutting cloth, suggesting the precise act of tailoring or shaping a garment to a specific size or pattern. This act of cutting and shaping to conform to a standard then evolved to symbolize the broader ideas of establishing order, regulating, controlling, and creating systems.
The visual connection between these components and the meaning is quite clear. The "knife" radical (刀) naturally suggests an action of cutting, shaping, or enforcing. When combined with the idea of 'fabric' or 'shaping,' it evokes tailoring or setting a specific design. This perfectly aligns with establishing a system or imposing a restriction – it's all about bringing things into a controlled, uniform state.
The kanji 制 has 8 strokes and is taught in Grade 5 of elementary school in Japan, making it a 教育漢字 (kyōiku kanji).
Readings
On'yomi (音読み) — Chinese-derived readings
On'yomi readings are derived from Chinese pronunciations and are primarily used when 制 appears as part of a compound word (熟語, じゅくご). For 制, the main on'yomi is セイ (sei). This reading is highly common and found in a wide array of everyday Japanese vocabulary, reflecting the kanji's diverse applications.
セイ (sei): This is the most common and virtually exclusive on'yomi for 制 in modern Japanese. It's used in words pertaining to systems, regulations, production, and control.
制度 (seido) — This compound refers to a system, institution, or organization. It denotes an established framework or arrangement, such as a legal or educational system. For example, 社会保障制度 (shakai hoshō seido) means "social security system."
制作 (seisaku) — Meaning production, creation, or a work (of art, film, music). Here, 制 implies the act of making or bringing something into existence in a structured manner. For instance, 映画制作 (eiga seisaku) means "film production."
制限 (seigen) — This word means restriction, limitation, or control. It signifies setting boundaries or conditions. For example, 時間制限 (jikan seigen) means "time limit."
Kun'yomi (訓読み) — Native Japanese readings
Kun'yomi readings are native Japanese pronunciations associated with the meaning of a kanji. While some older dictionaries or specialized contexts might list obscure kun'yomi for 制, such as けず-る (kezuru), these are not commonly encountered or taught as part of the N2 curriculum. For practical purposes at the JLPT N2 level, 制 is predominantly an on'yomi-only kanji. It appears almost exclusively in compound words with the reading セイ (sei). Therefore, you generally won't need to actively learn common kun'yomi readings for 制 for everyday Japanese usage at this level.

Memory Tip
To remember 制, visualize its components: the left part (suggesting fabric or shaping) and the right part, 刀 (knife). Imagine a skilled tailor using a knife (刀) to precisely cut and shape fabric to create a perfectly fitting garment. This act of careful, measured cutting isn't just about making clothes; it symbolizes the broader idea of establishing a pattern, bringing order, and exercising control. Just as the knife imposes a specific form, rules and systems restrict or regulate behavior and structures. Think: A knife helps control the shape of fabric to establish a uniform system.
