Meaning
The kanji 専 (セン, もっぱら) represents concepts like "exclusive," "specialized," "devoted," or "sole." It conveys a sense of singularity, concentration, or dedication to a specific task, area, or purpose. This often implies that something is restricted to, or focused on, one thing only. When you encounter 専, think of something unique, particular, or intently directed, rather than something shared, broadly applicable, or general.
Historically, the character's origin is quite fascinating. While its precise ancient form is debated, a common theory suggests 専 originally depicted a spinning wheel or a shuttle, used in the careful process of spinning thread. The upper part might represent the wheel or spindle, while the lower part, 寸 (sun), can mean "inch" but also refers to the "hand" or a "precise measurement." This suggests the meticulous manipulation required.
The act of spinning thread demanded intense focus, single-minded dedication, and specialized skill. From this visual, the meaning naturally evolved to represent "concentration," "devotion to one task," and "specialization." Thus, the kanji's visual shape deeply connects to the idea of exclusive focus on a particular skill or duty.
The kanji 専 has 11 strokes. It is designated as a Grade 6 kanji in the Japanese school system, meaning children typically learn it in their sixth year of elementary school.

Memory Tip
To remember 専, visualize its components. The bottom part is 寸 (sun), which means "inch" but can also represent a "hand" or a "small, precise measure." The top part resembles a complex "tool" or a "spinning wheel." Imagine a skilled artisan using their "hand" (寸) to precisely operate a "spinning wheel" (the top part).
This task requires complete "devotion" and "specialization" and is their "exclusive" domain. This image of careful, single-minded effort directly illustrates the kanji's meanings of "exclusive," "specialty," and "devoted."
