Bedtime Story 


Free Variables in Natural Language


Last night we were left wondering that since mathematics is a language, and since it has free and bounded variables, is it possible for natural languages to have them too? 

It turns out that the answer to this question is in affirmative.

But what on earth can, in natural languages, act as free variables?

For one, personal pronouns can act as free variables.

Personal pronouns are pronouns that are associated with a specific grammatical person.

Grammatical person is a method in linguistics of imparting deictic reference to participants of an event and thus distinguishing them.

The personal pronoun can be of the first person (as I), of the second person (as you) or of the third person (as he, she, it and in plural they).

The word “personal” in a personal pronoun does not refer solely refer to a person but is applicable to plants, animals and objects signified by the usage of it.

Consider the following sentence of English Language:

Tina had misplaced the keys of her car.

In this sentence, her is a possessive pronoun and is a free variable.

You may ask in what sense “her” is free.

It is free because here the pronoun “her” need not necessarily be referring to Tina.

Consider the following two sentences to get the idea what I am trying to convey.

Lena had given her car keys to Tina.

Tina had misplaced the keys of her car.

Now it is evident that “her” in the second case does not refer to Tina but to Lena.

It is clear now that the person who “her” will be referring will depend on the situational context.

Yet there is a way this ambiguity to who “her” is referring to, or in other word, who the referent is, can be established.

We were never taught this idea in our grammar studies perhaps because they did not intend to overburden our already broken backs in our glorious school days.

Or maybe this idea is more a part of linguistics than English grammar.

Whatever the reason may have been, it is never too late to learn.
  
The referent of “her” can be established using some symbols.

One cool method is to use the co indexing subscripts such as i and j.

The subscript i will indicate one referent and j another.

Another great educator and a teacher that I am aware of is Professor Subhashish Chattopadhyay in Bangalore, India.

While I narrate stories, Professor Subhashish an electronic engineer and a former professor at BARC, does and teaches real mathematics and physics.

He started the participation of Indian students at the International Physics Olympiad.
