corner of the eye
Refers specifically to the outer or inner corner of the eye. Often used in expressions like 眦を決する (to glare at someone with determination) or 眦が裂ける (to have one's eyes wide open in anger).
He glared at his opponent with fierce determination.
怒りで眦が裂けそうだった。
His eyes seemed to split at the corners from anger.
Kana spelling is practical when the kanji is obscure or for clarity.
Variant kanji form; less common than 眦.
The native word まなじり is formed from まな, an old combining form meaning “eye,” and しり, “rear or end,” with voicing to じり.
