expression, noun
Refers to the bed or place where someone is dying; often used in solemn or literary contexts.
彼は臨終の床で家族に看取られながら息を引き取った。
He passed away on his deathbed, surrounded by his family.
Means 'one's last moments' or 'deathbed' as an event; 臨終の床 is the noun phrase for the actual bed or location.
Compound of 臨終 (dying moments) + の (possessive particle) + 床 (bed). The expression is straightforward and transparent.
