Etymologically the word rubro comes from the Latin "rubrus" which means "red" "originally written in red" or "title". This term is morphologically speaking masculine and syntactically it is a noun; the dictionary of the Spanish Royal Academy exposes the word heading as an adjective to refer to red or red. But on the other hand, it is known as an item, in commerce, the group of consumer items that have a particularity among themselves, or that are related thanks to an activity itself. For this reason, in a general sense, item can be defined as that category that serves to join or gather within this, certain activities or objects that share one or more characteristics. The most common uses of this word lie in the commercial sphere and in newspaper classifieds; although it can be used in other areas.
When we speak of an item in relation to classifieds, it refers to each part or section where these sectors or advertisements are ordered, an example of this is when we find certain advertisements of different kinds in magazines and newspapers, called classifieds; that they contain different written offers, needs, notices, among others, on different topics such as jobs, to be offered or offered, of any kind; purchase and sale of vehicles, houses, articles of different types, rentals, health, etc.
Item can also refer to a label or title to which something is put. And in Argentina, item can mean that group of companies that are part of an area or zone that differs within the economic activity.
