Formal Languages
A language can be seen as a system suitable for expression of certain ideas, facts and concepts. For formalizing the notion of a language one must cover all the varieties of languages such as natural (human) languages and program- ming languages. Let us look at some common features across the languages. One may broadly see that a language is a collection of sentences; a sentence is a sequence of words; and a word is a combination of syllables. If one con- siders a language that has a script, then it can be observed that a word is a sequence of symbols of its underlying alphabet. It is observed that a formal learning of a language has the following three steps. 1. Learning its alphabet - the symbols that are used in the language. 2. Its words - as various sequences of symbols of its alphabet. 3. Formation of sentences - sequence of various words that follow certain rules of the language. In this learning, step 3 is the most di±cult part. Let us postpone to discuss construction of sentences and concentrate on steps 1 and 2. For the time being instead of completely ignoring about sentences one may look at the common features of a word and a sentence to agree upon both are just se- quence of some symbols of the underlying alphabet.
