capricious person; fickle person
Archaic noun for a person who is emotionally unstable or changes affections easily. Not used in modern everyday speech; encountered mainly in classical literature or historical contexts.
stylish person
Archaic sense for a person who is fashionable or elegant in appearance. This meaning is also obsolete and found only in older texts.
In classical literature, 徒人 was used as a term for a fickle person.
In the past, 徒人 also had the meaning of a stylish person.
The exact derivation is uncertain. The kanji 徒 can mean 'vain' or 'futile', and 人 means 'person', suggesting a person of fleeting or vain character. The reading あだびと likely combines あだ (vain, transient) with ひと (person), with rendaku voicing.
