noun
favorable wind; wind during rising tide
Poetic or literary term for a wind that blows favorably, especially associated with the rising tide. Rare in everyday conversation.
時津風が吹き始め、船は港を出た。
A favorable wind began to blow, and the ship left the harbor.
Common word for a favorable wind; 時津風 is a more poetic and specific term tied to tides.
Compound of 時 (toki, 'time' or 'tide') + 津 (tsu, archaic possessive particle) + 風 (kaze, 'wind'), literally 'wind of the tide'. The exact historical derivation is uncertain, but it is a classical poetic expression.
