Sense: adverb/1

Strangely is the most general and common of the three, simply noting that something is odd or surprising without suggesting an underlying cause. Inexplicably adds the nuance that the event cannot be accounted for by normal reasoning — it goes beyond mere oddity to imply the absence of any rational cause. Enigmatically suggests that someone or something deliberately presents a puzzle, often with an intriguing or cryptic quality. For example: 'The door was strangely cold to the touch.' 'The flight was inexplicably delayed for six hours with no announcement.' 'She smiled enigmatically and said nothing.'

Etymology

GreekLatinFrenchEnglish

Mysteriously traces back through French 'mystérieusement' to Latin 'mysterium' (a secret or religious rite), from Greek 'mystērion' (secret doctrine). Over time the focus shifted from religious secrets to anything puzzling or hard to understand. The '-ous' adjective suffix and '-ly' adverb suffix were added in English to form the modern adverb.
