love's zephyr; wind of love
A poetic, literary term for a gentle wind that stirs feelings of love, or the feeling of love itself likened to a breeze. Not an everyday word; used in songs, poetry, and romantic prose.
On a spring evening, a love's zephyr gently brushed my cheek.
Her singing voice soaked into my heart just like a wind of love.
Compound of 恋 (こい, 'love') and 風 (かぜ, 'wind'), literally 'love wind'. The exact origin is uncertain, but it follows a common pattern in classical Japanese poetry of personifying or naturalizing emotions through weather imagery.
