It is “to”.
You may find that this is a common and ‘not so special’ word, but, you are overlooking its meaning. There is much more to it with “to”.
This is one of the most particular word I ever ponder on. I called it a “word traveler”.
“To”, is preposition and adverb which I consider a rare gem. To me, it seemed to be smallest yet crucial piece of a mysterious puzzle that all human language holds. Many of the world’s languages do not have a similar existing word with the meaning by itself. The English language and its West Germanic cousins such as German (“zu” = “to”) should have this. Some of the languages, it serve as a suffix or a sort of conjunction within a word or sentence. However, in some others such as Chinese and Japanese, the word doesn’t exist. Although, I wish I knew more to show examples as such but couldn’t.
One word alone can convey one sentence to have a sense of place in anything. Its pragmatic essence that has a basis to form almost any message. I did wonder how far can one word has ever been more useful and what to think of it.
Think of many of the phrases using “to”. They all have a place or a task to go to. “To” is a very attentive word and it serves your decision to venture. If you say “I am going home/everywhere/anywhere/nowhere.”, those are the very few that has a special non-definitive claim of what or where.
There is also a contrast of how to place “to” by a verb. Placing “to” after a verb is state of realization (example, “…learn to be something”) and by placing “to” before the verb is the state of incompletion.(example, “…to learn something”). Don’t be confused with “to” between two verbs (example “I am going to learn.”) because there is a process of accomplishment; “To” should always be delivered by the sentence’s subject by first (action) verb.
We need “to”, otherwise there would be no direction. We need “to” do something. It is determined by “to” that there is an existence of purpose.
I have many more words to insight and be the one to better understand them. I intend to mean to.
With it, did you figure what is “to”?
