Therefore wait ye upon me, saith the Lord, until the day that I rise up to the prey: for my determination is to gather the nations, that I may assemble the kingdoms, to pour upon them mine indignation, even all my fierce anger: for all the earth shall be devoured with the fire of my jealousy. For then will I turn to the people a pure language, that they may all call upon the name of the Lord, to serve him with one consent. (Zeph 3:8-9)
For centuries, the concept of a perfect language, without any ambiguities and the like, has been searched out by people. Umberto Eco wrote an excellent book on this topic which I would recommend:
Such was also part-and-parcel of a lot of speculation on behalf of early Latter-day Saints (e.g., William Wines Phelps’ work on the Kirtland Egyptian Papers). Note the following discussions about the perfect language (often believed to be the “Adamic” language) spoken in the hereafter which will be without any of the imperfections of our earthly languages:
Orson Pratt:
Now let us touch, for a few moments, upon a principle in regard to the communication of knowledge between man and man, in his future state. We know how we communicate knowledge one to another here; it is by speaking, by writing, by arbitrary sounds that we convey our ideas one to another, and reveal knowledge, instruction, and truth one to another. This is a very imperfect medium of communication, consequently man progresses slowly, very slowly, indeed, in obtaining truth. But supposing that we could have revealed to us from on high a language more pure and heavenly, that is a perfect language, so far as it can be made perfect, and be adapted to our present state of existence; let such a language be revealed to us; let us learn it; let us obtain a knowledge of all the various symbols of the same, by which we could communicate our ideas one to another, perfectly, without any ambiguity or uncertainty in the ideas, would not this be a medium by which mankind could greatly enlarge their ideas and knowledge of things? Could not those that have progressed in the principles of truth and righteousness more readily impart their ideas to others? Now we find, in consequence of the imperfection of our language, that it is very difficult, indeed, to communicate readily our ideas to others, so that we have to spend years and years to instil into the minds of children and youth, some very easy and simple principles of knowledge. It is in one sense owing to the weakness of the capacity and intellect in early age, but it is still more owing to the imperfection of language by which these ideas are communicated. [The speaker here asked a blessing upon the bread.] We were speaking upon the imperfect medium, here in this life, by which we convey our ideas one to another. Let us now compare our present means of obtaining knowledge with the facilities which are no doubt, in store for the people of God. Will there be a pure language restored? There will; through the testimony of the prophets. We are also told that tongues shall cease. We are to understand by this that the great varieties of languages and tongues that have existed on the earth for many ages, are to be done away; they are to cease; now something must take the place of those imperfect, confused languages and tongues. What is that something? It is a language that is spoken by higher orders of beings than ourselves; that is, beings that have progressed further thorn ourselves; it is that same language that was spoken for nearly two thousand years after the creation; that was spoken by Adam and by his children, from generation to generation that came down to the flood, and was taught extensively among the children of Noah until the Lord by a direct miracle caused the people to forget their own mother tongue, and gave them a variety of new tongues that they had no knowledge of, and by this means scattered them abroad upon the face of the whole earth; and now that same Being that destroyed the memory of the people at the building of the tower, so that they could not remember their own mother tongue, and the same Being that gave to them new languages and tongues, will operate again by His power to do away this curse, for I consider it a curse, and the blessing will be as great and as extensive as the curse, in destroying it from the face of the earth. This is a poor medium of communication between man and man. Whether this pure language here spoken of, which is to be spoken here upon the earth among mankind in their mortal state, is to be as perfect as the language that has to be spoken in our immortal state, is not for us to say; but still we may draw some conclusions upon this matter, from the fact that things in the eternal world will in some measure be different from what they are here. For instance; how do you suppose that spirits after they leave these bodies, communicate one with another? Do they communicate their ideas by the actual vibrations of the atmosphere the same as we do? I think not. I think if we could be made acquainted with the kind of language by which spirits converse with spirits, we would find that they do not communicate their ideas in this manner; they have a more refined way; I mean that portion of them that are in the school of progress; they have undoubtedly a more refined system among them of communicating their ideas. This system will be so constructed that they can, not only communicate at the same moment upon one subject, as we have to do by making sounds in the atmosphere, but communicate vast numbers of ideas, all at the same time, on a great variety of subjects; and the mind will be capable of perceiving them. Perhaps there may be some who consider this altogether an improbability. They may consider it very improbable that the mind should be able to take in a vast collection of ideas, on different subjects, all at once, and be able to digest and comprehend them; if the mind has such faculty as this, then there must necessarily be a language adapted to such a capacity of the mind; not an imperfect medium of communication to convey a few simple ideas upon one subject at a time, as is done here, but a language exactly adapted to the capacity; if the capacity, is greater, then the language must be more refined than what it is here, in order to communicate in the same ratio that the capacity is capable of receiving and understanding. It is impossible for man to communicate, by our present language, any more than one chain of ideas at the same time. There may be other ideas suggested to the individual who is hearing, but the ideas of the individual who is speaking are always in one line, giving one idea at a time; and the mind seems hardly capable here in the mortal tabernacle, for some reason, of receiving more than one idea at a time, or at least a very few, and such ideas follow each other in quick succession. In the spirit state, we have reason to believe, that inasmuch as there is such a vast field of knowledge to be learned, their medium of communication will be adapted to the nature and capacity of the mind to grasp in a variety of subjects and digest them all at once. Well inquires one, "Can you imagine up any such system, or language in this, world?" I can imagine up one, but it cannot be made practicable here, from the fact that the mind of man is unable to use it. For instance, the Book of Mormon tells us, that the angels speak by the power of the Holy Ghost, and man when under the influence of it, speaks the language of angels. Why does he speak in this language? Because the Holy Ghost suggests the ideas which he speaks; and it gives him utterance to convey them to the people. Suppose the Holy Ghost should suggest to the mind of an individual a vast multitude of truths, I mean when in the spiritual state, and he wished to convey that intelligence and knowledge to his fellow spirit; suppose, instead of having arbitrary sounds, such as we have here, to communicate these ideas, that the Holy Ghost itself, through a certain process and power, should enable him to unfold that knowledge to another spirit, all in an instant, without this long tedious process of artificial and arbitrary sounds, and written words. The fact is, if celestial spirits were so organized, and so constructed, as to close up their own ideas in their own bosoms, from those in a lower condition, or to disclose them at their own pleasure, according to the mind and wisdom of the Holy Ghost, and others were so organized and constituted as to receive these ideas by the power of the Holy Ghost, it would be just as good a communication between man and man—between spirit and spirit, as any other medium, and perhaps far better. Now, I have quite an idea that this will be one of the great helps in the eternal world, by which knowledge will be poured out more abundantly upon the mind of man; it will be by this aid; by the power of the Holy Spirit, so that they will progress faster than here, they will learn more rapidly; the intellectual powers will be more expanded.

Brigham Young:
You have heard the testimonies of some of our returned missionaries today, from which you can judge that their hearts are greatly comforted. Some of them have expressed their delight, at having the privilege of beholding this congregation of Saints in Zion. It is a great satisfaction, to look upon those who love the Lord with an undivided affection; it is a great satisfaction to speak to them, and to hear them speak; and, were I to have my choice, I would rather hear men testify to the truth by the spirit of truth, than to speak myself. In my reflections I foresee a time, when we shall be able to communicate with each other easier and with much more pleasure and satisfaction than we now do; but we will then use a different language. Although the language we now speak is as good as any language that has yet come to our knowledge, still it is very meagre, and limited in its range and power, and though it is a good medium at ordinary times, yet ,it comes very far short of being such a medium, as man needs to convey thoughts, when he is inspired by the power of God, through the gift of the Holy Ghost, and is fall of the revelations of Jesus. It is written "Therefore, wait ye upon me, saith the Lord, until the day that I rise up to the prey: for my determination is to gather the nations, that I may assemble the kingdoms, to pour upon them mine indignation, even all my fierce anger: for all the earth shall be devoured with the fire of my jealousy for then will I turn to the people a pure language, that they may all call upon the name of the Lord, to serve him with one consent." When a man rises up to speak in the name of the Lord, and is filled with the light, and the intelligence and power which cometh from God, his countenance alone will convey more, to those who are inspired by the same spirit, than can possibly be conveyed, by the words of any language now used by mankind. (JOD 10:363 | November 6, 1864)
