Lexember 14th: ‘thunderstruck’

Swēva þīfuns þrundnas

/ˈswai̯.va ˈθiːfuns ˈθrund.nɑs/ adj.a thunderstruck, amazed, astonished, bewildered.

A phrasal adjective (the word þrundnas is declined to agree with its noun or pronoun), this is literally the phrase “as though struck by thunder,” i.e. ‘thunderstruck’.

From swēva ‘as though’ (from swē ‘so, as, like’ and iva ‘if, whether’) and þifuns, genitive of þīfua ‘thunder’, and þrundnas, past participle of þrindna ‘to strike’.
