博学多才
haku.gaku.ta.sai
Literally: acclaimed – study – many – talent
Alternately: Possessing an extensive store of knowledge and a range of skills. Talented and educated. A “Renaissance man.”
Notes: This is another compound formed by simply joining two two-character words together. Common variants may use 識 (shiki), “knowledge,” in place of either 学 or 才.

“It’s not that I know everything, it’s just that I know that.”
