year of a large crop; bumper year
Refers to a year when fruit trees or other crops bear an especially abundant harvest. Often used in agricultural or seasonal contexts.
This year is a bumper year for mandarins, and every tree is laden with fruit.
Bumper years and lean years often alternate.
Standard kanji spelling; 生り conveys 'bearing fruit'.
Variant spelling with kana for the first part; less common but still used.
Compound of 生り (nari, 'bearing fruit', from verb 生る naru) and 年 (toshi/doshi, 'year'). The reading なりどし is a straightforward combination.
