scarily

The adverb 'scarily' is built upon the core adjective 'scary', which itself derives from the verb 'scare'. The verb 'scare' entered English from Old Norse skirra, meaning 'to frighten off', a term with a clear sense of causing sudden fear. The adjectival suffix '-y' (from Old English -ig) was added to form 'scary', meaning 'causing fright'. Finally, the prolific Old English adverbial suffix '-ly', originally meaning 'having the body or form of', was appended to create 'scarily', specifying that an action is performed in a frightening manner. In modern colloquial use, this literal sense has been extended through hyperbole to serve as an intensifier, meaning 'extremely', leveraging the root's inherent connotation of strong emotional impact.
