Refers to various small, scattered things or details; often used in expressions like 端々に (in various places) or 端々まで (down to the last detail).
部屋の端々にほこりがたまっていた。
Dust had accumulated in every corner of the room.
彼は契約書の端々まで注意深く読んだ。
He carefully read every last detail of the contract.
Kana spelling; used when the kanji is avoided or for clarity.
Alternate spelling without the iteration mark; less common but still used.
Reduplication of 端 (はし, 'edge, end'), with the reading はしばし arising from rendaku (sequential voicing). The kanji spellings 端々 and 端端 both represent this reduplication.
