sea-zoned

'Where the soul's glory shines with clearer beam, / Than in our sea-zon'd bulwark of the west' (Llangollen Vale, p. 9)

1795

OED1/2 has several examples of such compounds (s.v. sea, sense 21) - sea-bathed, -blown, -bounded, -boke, -circled, -deserted, -divided, -driven, -encircled, -fed, -lulled, -scented, -strewn, -sucked, -tossed, -wrecked - but not this one.

choir, v.

'angels choir him, while he waits for THEE' (Elegy on Captain Cook, p. 18)

1780

OED1/2 does not record this transitive use, 'sing in praise of'. Sense a = 'intr. To sing, as a choir; to sing in chorus' (OED quotations dated 1596, 1610, 1804); sense b (trans.) is undefined, and illustrated with one quotation only - from Seward's mentor Erasmus Darwin: '1791 E. DARWIN Bot. Gard. I. 18 To the sacred Sun, Spontaneous Concords quired the matin strain'. But choir here takes what is sung as its grammatical subject, not the person to whom the song is address.

unsubside

'no sad course of desolated hours / Here vainly nurse the unsubsiding woes' (Llangollen Vale, p. 11)

1796

No OED entry for unsubside or for unsubsiding. There is one for unsubsided, which is furnished with two quotations, dated 1804 and 1815.
