What does unnerving mean?
Unnerving means causing an uncomfortable feeling of uncertainty, anxiety, or apprehension. The word is especially useful for describing experiences, sounds, silences, places, or behaviors that seem threatening or difficult to interpret without necessarily involving immediate physical danger. A situation may be called unnerving when it unsettles the expectations or emotional security of the people encountering it. The adjective can appear before a noun, as in “an unnerving prospect,” or after a linking verb, as in “the prospect was unnerving.” Compared with simply worrying or alarming, unnerving often emphasizes the lingering sense of unease that something creates. It is equally natural in British and American English and is often modified by adverbs such as “slightly,” “deeply,” or “increasingly.” Although usually an adjective, unnerving is also the present participle of the verb unnerve, meaning to deprive someone of confidence or composure. The word's force comes from its combination of the negative prefix un- with nerve, suggesting not merely nervousness but the loss of a feeling of safety or steadiness.

Etymology of unnerving
Unnerving is the present participle of the English verb unnerve and came to be used independently as an adjective for something that causes unease. The verb was formed with the prefix un- and the noun nerve, which comes through Old French nerf from Latin nervus, meaning “sinew” or “tendon” and by extension physical strength or vigour. The same Latin root underlies related English words such as nervous and the botanical term nervure.
