The word "単一" (たんいつ) means "single," "simple," or "sole." It is often used to emphasize that something consists of only one element or factor, without any mixture or complexity. This word is common in formal or academic contexts, such as scientific explanations, technical descriptions, or analytical discussions.

Usage Notes
When using "単一," speakers imply exclusivity or simplicity. It is often contrasted with words like "複数" (multiple) or "多様" (diverse).
Be careful not to confuse "単一" with "単純" (たんじゅん), which means "simple" but can imply lack of complexity or sophistication, whereas "単一" stresses singularity or uniqueness.
"単一" is more formal and less common in casual conversation but important in written and professional Japanese.
