neurotically

The word's journey begins with the ancient Greek neuron, meaning "nerve" or "sinew," which passed into medical Latin. The suffix -osis (from Greek) denoted a state or condition, leading to the 18th-century coinage "neurosis" for a disorder of the nerves. The adjective "neurotic" was formed by adding the adjectival suffix -ic to this base. Finally, the modern adverb "neurotically" was created by appending the productive adverbial suffix -ally, which itself is a fusion of the adjectival -al and the adverbial -ly. Thus, the term evolved from a literal reference to physical sinews to describe a psychological condition, and finally to an adverb characterizing a specific manner of behavior linked to that condition.
