This formal language expresses natural numbers, well-formed additions, and well-formed addition equalities, but it expresses only what they look like (their syntax), not what they mean . For instance, nowhere in these rules is there any indication that "0" means the number zero, "+" means addition, "23+4=555" is false, etc.
One example showing the difference between respectful and common language can be seen in the word sleep. The word for ' sleep ' using common language is maúr, while it is saipash using respectful language. [12] Along with the respectful language, there are formal greetings called tiirou or fairo that are used in meetings and gatherings. In ...
Syntax is usually associated with the rules (or grammar) governing the composition of texts in a formal language that constitute the well-formed formulas of a formal system. In computer science, the term syntax refers to the rules governing the composition of well-formed expressions in a programming language. As in mathematical logic, it is ...
A word may be phonologically well-formed, meaning it conforms to the sound pattern of the language. For example, the nonce word wug coined by Jean Berko Gleason is phonologically well-formed, so informants are able to pluralize it regularly. [1] A word, phrase, clause, or utterance may be grammatically well-formed, meaning it obeys the rules of ...
Suppose, for example, that one wants to define the well-formed formulas (wffs) of a new formal language, L, with only a single logical operation, negation, via the following recursive definition: Any lowercase Roman letter (with or without subscripts) is a well-formed formula (wff) of L .
An example of such a language is Turkish, where for example, the word evlerinizden, or "from your houses", consists of the morphemes, ev-ler-iniz-den with the meanings house-plural-your-from. The languages that rely on morphology to the greatest extent are traditionally called polysynthetic languages. They may express the equivalent of an ...

A formal language is an organized set of symbols, the symbols of which precisely define it by shape and place. Such a language therefore can be defined without reference to the meanings of its expressions; it can exist before any interpretation is assigned to it—that is, before it has any meaning. First-order logic is expressed in some formal ...
