Meaning
The kanji 丁 (chō, tei, hinoto) boasts a diverse range of meanings, often shifting based on context and its accompanying characters. At its core, 丁 can represent a "block" or "piece" of something, like a block of tofu (一丁). It also functions as a counter for various items, including knives, guns, and blocks of specific goods. Beyond these tangible meanings, 丁 is frequently encountered when referring to streets, districts, or sections of a town, such as in addresses like 銀座一丁目 (Ginza 1-chome). In the context of games like dice, it signifies an "even number." Historically, and in traditional East Asian calendrical systems, 丁 serves as the fourth of the ten celestial stems (十干, jikkan), read as ひのと (hinoto).
The origin of 丁 likely traces back to a pictograph. Scholars suggest it originally depicted a nail, a cleat, or a wedge-shaped object. Its simple, angular shape indeed resembles a nail's head and shaft, or a tool. This visual connection easily extends to the idea of a "piece" or "block" of material. Furthermore, its T-shape can also be seen to visually align with a T-junction or a crossroad, connecting it to meanings like "street" or "district." The abstract concept of an "even number" might stem from the idea of pairing or dividing blocks equally. Composed of just two strokes, 丁 is visually straightforward. Yet, its semantic breadth is quite extensive, warranting its N1 classification due to its nuanced applications and historical references.

The kun'yomi for 丁 is quite specific and rooted in ancient Japanese calendrical systems, making it less common in everyday spoken language but vital for historical and cultural contexts.
ひのと (hinoto)
This is the main kun'yomi for 丁, specifically referring to the fourth of the ten celestial stems (十干, jikkan). These stems, when combined with the twelve terrestrial branches (十二支, jūnishi), form the 60-year sexagenary cycle (干支, eto). This cycle was used in ancient East Asian calendars, astrology, and philosophy. In this system, 丁 (ひのと) represents the element of "Fire" (火) in its younger or "little brother" (弟) form, sometimes interpreted as "Small Fire." It's primarily encountered when discussing historical dates, traditional divination, or specific philosophical concepts.
- 丁 (hinoto) — the fourth of the ten celestial stems. This represents its standalone usage within this specific context.

Memory Tip
To remember the kanji 丁, visualize its simple, two-stroke form as either a sturdy nail or a T-shaped intersection. For the "nail" image, think of it as a basic "block" or "piece" of material, like a nail itself, leading to its use as a counter for various items (一丁の豆腐). For the "T-junction" image, the shape directly corresponds to its meaning in 丁字路 (T-junction) and its role in street addresses like 丁目. You can create a story: You're at a 丁字路 where a large "block" of tofu (一丁) is sold. You stop 丁度 (just right) at the intersection to buy it, always being 丁寧 (polite) to the vendor.
