ordinary person; mediocre person
A somewhat literary or old-fashioned term for a person of average ability or no special talent. Often used in contrast to 天才 (genius) or 偉人 (great person).
He humbly said he was just an ordinary person.
Composed of 凡 (mediocre, ordinary) and 骨 (bone, frame). The exact historical derivation is uncertain; the combination suggests a person of ordinary 'make' or caliber.
