稍许 is an adverb meaning 'a little' or 'slightly', used to indicate a small degree or amount. It combines 稍 (shāo), which means 'a little' or 'somewhat', and 许 (xǔ), which in this context functions as a classical particle reinforcing the sense of modest quantity — together, they form a fixed, literary-leaning expression that softens statements without sounding vague.

This word is commonly used in spoken and written Chinese to express mild intensity — for example, when describing slight changes in emotion (e.g., feeling slightly tired), minor adjustments (e.g., lowering volume a little), or subtle differences (e.g., a slightly higher price). It often appears before verbs or adjectives and carries a polite, restrained tone, making it suitable for formal or thoughtful speech — though it’s also natural in everyday conversation among educated speakers.
