nominative case
Definition - The grammatical case that indicates the subject of the verb.

1. English normally expresses this with word order. In highly inflected languages, such as Latin, this is shown by modifying word endings.

Example -
In the sentence Bob ate Dick, the word order tells us that Bob is the subject and Dick is the object.

Etymology -
The word derives via Middle French from the Latin nominativus, pertaining to naming.

Oxford English Dictionary -
Its first citation is from 1387:
"Þat ylond of Ynde hatte Tilis in þe nomenatyf caas; and þe ilond of occean hatte Tyle in þe nominatyf caas."
(Trevisa Higden (Rolls) I. 327 )
