The accusative absolute is a grammatical construction found in some languages.

In ancient Greek, the accusative case is used adverbially with participles of impersonal verbs. It is similar in usage to the genitive absolute.^[1] For example:

συνδόξαν	τῷ	πατρὶ	καὶ	τῇ	μητρὶ	γαμεῖ	τὴν	Κυαξάρου	θυγατέρα
seeming good-acc	the-masc.dat.sg	father-dat	and	the-fem.dat.sg	mother-dat	marries	the-fem.acc.sg	Cyaxares-gen	daughter-acc
"It seeming good to his father and mother, he marries the daughter of Cyaxares." (Xenophon, Cyropaedia 8.5.28)

In German, a noun phrase can be put in the accusative to indicate that the subject of the sentence has the property described.^[2] For example:

Neben	ihm	saß	der	dünnhaarige	Pianist,	den	Kopf	im	Nacken,	und	lauschte.
next to	him	sat	the	thin-haired	pianst	the-masc.acc.sg	head	in the	neck	and	listened
"The thin-haired pianist, his head hanging (lit. his head in his neck), sat next to him and listened."
