In a way that is dizzying or causes dizziness; to an extreme or overwhelming degree.
Formed from 'dizzying' (the adjective/present participle form of dizzy) plus the adverbial suffix '-ly.' This is a double suffix construction showing how English can layer multiple grammatical endings.
When you stack suffixes like '-ing' and '-ly,' you get 'dizzyingly'—English loves building longer words by adding layers! Some languages consider this inefficient, but English speakers are perfectly comfortable with constructions like this that express complex shades of meaning.
