仅此 means 'only this' or 'nothing more than this' and functions primarily as an adverb to emphasize exclusivity or limitation. The character 仅 (jǐn) means 'only' or 'merely', while 此 (cǐ) means 'this'. Together, they form a concise, formal expression indicating that something is strictly limited to the item, action, or situation just mentioned — nothing else is included, allowed, or relevant.

This phrase is commonly used in written Chinese, official notices, instructions, or polite refusals where precision and clarity are important. It often appears at the beginning or end of a sentence and carries a slightly formal or literary tone. Learners should note that 仅此 is not typically used in casual spoken conversation; instead, phrases like 就这么多了 or 只有这个 are more common in everyday speech.
