someone of importance; a person of some standing
Used to describe a person who has achieved a certain level of recognition or status in a field. Often implies they are not the top but still notable.
He is known as a person of some importance in the industry.
She is now a person of some standing herself.
Standard kanji spelling; 一角 means 'one corner' but here it's part of the fixed phrase meaning 'a person of some standing'.
Kana spelling of the first part; used when the kanji 一角 might be misread as いっかく.
The phrase combines 一角 (ひとかど, 'one corner') with 人物 (じんぶつ, 'person'). 一角 here figuratively means 'a certain degree' or 'a respectable position', so the whole phrase means 'a person of some standing'. The exact origin of this figurative use is uncertain.
