真(っ)

真(っ) is a powerful prefix used to intensify adjectives and some phrases, meaning completely, absolutely, or very much. It often modifies color or appearance (真っ赤, 真っ白), or marks a straightforward action (真っ直ぐ進む). It can also appear in fixed expressions like 真っ先に. It lends a strong, dramatic sense, so use it for vivid descriptions or emphatic statements, typically in informal to neutral contexts. When used with na-adjectives or nouns, it becomes 真っ白な, 真っ黒な, etc.
