   What is a language family?

Most languages belong to language families. A language family is a group of related languages that developed from a common historic ancestor, referred to as protolanguage (proto– means ‘early’ in Greek). The ancestral language is usually not known directly, but it is possible to discover many of its features by applying the comparative method that can demonstrate the family status of many languages. Sometimes a protolanguage can be identified with a historically known language. Thus, provincial dialects of Vulgar Latin are known to have given rise to the modern Romance languages, so the *Proto-Romance language is more or less identical to Latin. Similarly, Old Norse was the ancestor of Norwegian, Swedish, Danish and Icelandic. Sanskrit was the protolanguage of many of the languages of the Indian subcontinent, such as Bengali, Hindi, Marathi, and Urdu. Further back in time, all these ancestral languages descended, in turn, from one common ancestor. We call this ancestor *Proto-Indo-European (PIE). Language families can be subdivided into smaller units called branches. For instance, the Indo-European family has several branches, among them, Germanic, Romance, and Slavic.

   How do linguists establish relationships among languages?

Sometimes it is relatively easy to establish relationships among languages. Let us look at the Romance languages. We know that Italian is a descendant of Latin, a language that was spoken in Italy two thousand years ago, and one which left a great number of written documents. The Roman conquest helped spread Latin throughout Europe where it eventually developed into regional dialects. When the Roman Empire broke up, these regional dialects evolved into the modern Romance languages that we know today: French, Italian, Portuguese, Spanish, and others. These languages form the Romance branch of the Indo-European language family. By looking at the word for ‘water’ in three Romance languages, one can easily see the similarities among them.

Italian acqua
Spanish agua
Portuguese agua
   What if the ancestral language left no records?

The case with Romance languages is unusually easy because their common ancestor — Latin — left many written documents. In most cases, however, the ancestral language was not written. As a result, linguists look at similarities among its modern descendants to establish common origins. Take a look at these examples:

English
water
German
wasser
Danish
vand
Russian
voda
Polish
woda
Czech
voda

It is clear that the word for ‘water’ looks very similar within each group, but not quite as similar across groups. Languages in the first group belong to the Germanic branch of the Indo-European language family. Languages in the second group belong to the Slavic branch. Although there are no written records of the ancestral *Proto-Germanic or *Proto-Slavic languages, we have to assume that these two ancestral languages must have existed at some time, just like Latin did.

   Where do these mystery languages belong?

Here is the word for ‘water’ in two more languages. Do you think these languages belong to any of the branches above?

Latvian udens
Albanian uje
Basque ur

As it turns out, Latvian belongs to the Baltic branch of the Indo-European language family, Albanian has no close relatives and does not belong to any of the branches of the Indo-European language family, and Basque does not belong to any language family at all. In fact, it is a language isolate, i.e., a language that cannot be reliably assigned to any established language family.

   What if there are no records, and we know little about the languages?

In many parts of the world, there are no written records, and we don’t know enough about the languages themselves. Consequently, we have to resort to grouping languages on the basis of geography. This is the case with many of the aboriginal languages of Australia, the native Indian languages of the Americas, the tribal languages of Africa, and countless other languages all over the world.

   How many language families are there?

According to Ethnologue (16th edition), there are 147 language families in the world. This figure may not be precise because of our limited knowledge about many of the languages spoken in the most linguistically diverse areas of the world such as Africa. The actual number of families, once these languages are studied and relationships among them are established, will undoubtedly keep changing.

   World’s largest language families

The largest language families (those with over 25 languages) are listed below (Ethnologue). There are 6,523 languages in this group, and together they account for close to 95 percent of all world languages (assuming that there are some 6,900 languages in the world). The remaining families account for only 5 percent of the world languages. In addition, there are 53 languages considered unclassified.

Onscreen Keyboard

What does Onscreen Keyboard mean?

An onscreen keyboard is a software-based keyboard that is available in most operating systems, especially Microsoft Windows, and in other applications. An onscreen keyboard allows users to type text using a joystick or a pointing device. Apart from improving input options for users who are physically challenged, it also serves as an alternative to a physical keyboard.

Onscreen keyboards are also known as software keyboards or soft keyboards.

Onscreen Keyboard

An onscreen keyboard displays a virtual keyboard on the screen for users to enter input. It can be operated with the help of any pointing device such as a mouse, pen, joystick, etc. The keyboard is often resizable and customizable, allowing the typing mode, font, etc., to be changed as needed. In certain onscreen keyboards, especially those from Windows 7 and later versions, they are equipped with a predictive text engine, which helps in predicting the words the users may type.

There are several ways an onscreen keyboard can come in handy. It is useful, for example, for physically challenged users who have difficulty using a physical keyboard. It can also be used as an alternative or a temporary keyboard in case the physical keyboard becomes defective. Using an onscreen keyboard also prevents keystrokes from being captured by certain spyware programs such as keyloggers.

However, as typing on an onscreen keyboard is slower and more difficult than on a physical keyboard, most onscreen keyboards feature predictive text input.
