Koe sezu wa ikade shiramashi harugasumi hedatsuru sora ni kaeru karigane - Kinyo Wakashu(English Translation & Meaning)

声せずはいかで知らまし春霞
へだつる空に帰る雁がね

Roma-ji: Koe sezu wa ikade shiramashi harugasumi hedatsuru sora ni kaeru karigane
English Translation: Had they made no sound,
how could I have ever known
behind spring's haze
in the sky that it conceals
the wild geese returning north
Meaning: Had they not called out, how could I have known of the wild geese flying home through a sky hidden behind the spring haze?
Commentary: Book One Spring Poems 27

The poet learns from their cries that wild geese are flying north across a sky where the spring haze hides them from view. Knowing the unseen by sound, it forms a pair of returning-geese poems with the next.

First line, 'koe sezu wa', is a supposition: had there been no voice.
Second line, 'ikade shiramashi', is counterfactual: how could I have known, meaning I could not. The poem breaks after the second line.
Third line, 'harugasumi', is set as the veil that hides the geese.
Fourth line, 'hedatsuru sora ni', means in the sky the haze shuts off.
Final line, 'kaeru karigane', names the geese returning north in spring, ending on a noun. The next poem, 28, picks up the word karigane.
