What does unambiguously mean?
Unambiguously is an adverb meaning in a way that is completely clear and cannot reasonably be understood in more than one way. It is often used to describe instructions, descriptions, decisions, evidence, or official statements that leave no uncertainty about their meaning or intended effect. The word is especially common in legal, academic, technical, and administrative contexts, where exact interpretation is important. Compared with “clearly,” it carries a stronger emphasis: it suggests not merely that something is easy to understand, but that the wording deliberately excludes every plausible alternative reading. This force can be useful when resolving confusion, defining a position, or confirming an important fact, although it may sound overly emphatic in ordinary conversation. Unambiguously is the adverbial form of “unambiguous” and is closely related in meaning to “unequivocally.”

- In a manner that is clear, definite, and not open to more than one interpretation.

"The witness described the sequence of events unambiguously."
"The treaty sets out the restrictions unambiguously, so national governments have little room to interpret them differently."
The prefix un- does more than remove doubt: it signals a statement forceful enough to leave no room for interpretation.

Where does unambiguously come from?
Unambiguously is formed from “unambiguous” with the adverbial suffix -ly. The family derives from Latin ambigus, meaning “of two minds” or “ambiguous,” which is associated with ambi- (“both”) and agere (“to drive” or “do”). English borrowed ambiguous and ambiguity from Latin, and the prefixed form unambiguous developed later to express the opposite meaning. The adverbial form unambiguously follows the ordinary English pattern of adding -ly to an adjective.
