In linguistics, grammatical mood (sometimes mode) is a grammatical (usually morphologically marked) feature of verbs, used to signal modality.[1][2]:p.181;[3] That is, it is the use of verbal inflections—known as grammatical conjugation—that allow speakers to express their attitude toward what they are saying (for example, whether it is intended as a statement of fact, of desire, of command, etc.). Less commonly, the term is used more broadly to allow for the syntactic expression of modality — that is, the use of non-inflectional phrases. Mood is distinct from grammatical tense or grammatical aspect, although the same word patterns are used to express more than one of these meanings at the same time in many languages, including English and most other modern Indo-European languages. (See tense–aspect–mood for a discussion of this.) Some examples of moods are indicative, interrogatory, imperative, emphatic, subjunctive, injunctive, optative, potential. Infinitive is a category apart from all these finite forms, and so are gerunds and participles. Some Uralic Samoyedic languages have more than ten moods; Nenets has as many as sixteen. The original Indo-European inventory of moods consisted of indicative, subjunctive, optative, and imperative. Not every Indo-European language has each of these moods, but the most conservative ones such as Avestan, Ancient Greek, and Sanskrit have them all. English has the indicative, imperative, emphatic, and subjunctive moods; others, such as the conditional, do not appear as morphologically distinct forms. Not all of the moods listed below are clearly conceptually distinct. Individual terminology varies from language to language, and the coverage of (e.g.) the "conditional" mood in one language may largely overlap with that of the "hypothetical" or "potential" mood in another. Even when two different moods exist in the same language, their respective usages may blur, or may be defined by syntactic rather than semantic criteria. For example, the subjunctive and optative moods in Ancient Greek alternate syntactically in many subordinate clauses, depending on the tense of the main verb. The usage of the indicative, subjunctive, and jussive moods in Classical Arabic is almost completely controlled by syntactic context. The only possible alternation in the same context is between indicative and jussive following the negative particle l?.


Product classification

A product can be classified as tangible or intangible. A tangible product is a physical object that can be perceived by touch such as a building, vehicle, gadget, or clothing. An intangible product is a product that can only be perceived indirectly such as an insurance policy.
       Intangible Data Products can further be classified into Virtual Digital Goods ("VDG") that are virtually located on a computer OS and accessible to users as conventional file types, such as JPG and MP3 files, without requiring further application process or transformational work by programmers, and as such the use may be subject to license and/or rights of digital transfer, and Real Digital Goods ("RDG") that may exist within the presentational elements of a data program independent of a conventional file type, commonly viewed as 3-D objects or a presentational item subject to user control or virtual transfer within the same visual media program platform. Open Source Code, GNU Linux, or even Android, may manipulate and/or convert base Virtual Digital Goods ("VDG") into process-oriented Real Digital Goods ("RDG"), as part of an application process or manufactured service that may be viewed on Personal Data Assistant ("PDA") or other hand-held tangible devices or OS computer.
           A third type in this is services. Services can be broadly classified under intangible products which can be durable or non durable.Services need high quality control, precision and adaptability. The main factor about services as a type of product is that it will not be uniform and will vary according to who is performing, where it is performed and on whom/what it is being performed.
 Product Model

         A manufacturer usually provides an identifier for each particular type of product they make, known as a model, model variant, or model number. For example, Dyson Ltd, a manufacturer of appliances (mainly vacuum cleaners), requires customers to identify their model in the support section of the website.[15] Brand and model can be used together to identify products in the market. The model number is not necessarily the same as the manufacturer part number (MPN).[16]
          Because of the huge amount of similar products in the automotive industry, there is a special kind of defining a car with options (marks, attributes), that represent the characteristics features of the vehicle.
