erudition and extensive knowledge; widely read and well-informed
A yojijukugo describing a person who has read widely and possesses deep, broad knowledge. Often used in formal or literary contexts to praise someone's learning.
He is widely read and well-informed, and can answer any question.
博覧多識の人は、話していてとても勉強になる。
Talking with a person of extensive knowledge is very educational.
博学 is a more common word for 'erudition' or 'wide learning', while 博覧多識 is a formal yojijukugo emphasizing both wide reading and deep knowledge.
博識 means 'extensive knowledge' and is more frequently used than 博覧多識, which adds the nuance of having read widely.
A yojijukugo composed of 博 (wide, extensive), 覧 (see, read), 多 (many), and 識 (knowledge). The exact historical origin is uncertain, but it follows a common pattern of four-character compounds expressing breadth of learning.
