Did Proto-Indo-European Use the Letter J?

Proto-Indo-European (PIE) was a pre-literate language, existing over three and a half millennia before the invention of the Latin alphabet. This means that the concept of a written language, let alone specific letters like 'J', would be far removed from the time period. However, as with many ancient and reconstructed languages, scholars often use symbols to represent sounds. Let’s explore this question in detail.

Proto-Indo-European and the Latin Alphabet

Proto-Indo-European was a language that existed long before the Latin alphabet was invented. The Latin alphabet, which includes the letter 'J', was not conceived until much later. Before the 16th century, 'J' and 'I' were considered interchangeable. Even today, in some languages, 'I' and 'J' can represent different sounds. This raises the question: did PIE use the letter 'J'? The answer is no, it did not use any letter because it existed in a pre-literate society without a written language.

Phonetic Representation in PIE

Proto-Indo-European did utilize phonetic representations for sounds, but these were not the same as letters. There was a phoneme /j/ (a palatal approximant or a consonantal y sound) that could be transcribed using the symbol 'y'. This sound is represented by 'j' in modern English orthography, but that orthography is a later development. The exact transcription in PIE would vary based on the specific language and time period.

Evolution of the J-Letter

The letter 'J' as we know it today evolved from the letter 'I' in the Latin alphabet. The distinction between 'I' and 'J' became more pronounced only in the 16th and 17th centuries. This development meant that early reconstructions of PIE, done in the 19th century, used the letter 'i' for /j/. Later, the letter 'y' became a more common choice to represent the phoneme /j/. It's important to note that these choices were not inherent to PIE itself but rather to the way scholars reconstructed and transcribed the language.

Reconstruction and Scholarly Practices

When reconstructing Proto-Indo-European, scholars use symbols and letters to represent sounds. However, this is an exercise in reconstruction, not an actual written language that PIE speakers used. August Schleicher, one of the pioneers in PIE reconstruction, used the letter 'j' to represent the phoneme /j/. This was later supplanted by 'i' in the latter half of the 19th century. By the 20th century, 'y' became the more common choice.

Proto-Indo-European speakers did not use any letters because they were part of a pre-literate society. Therefore, the absence of the letter 'J' is not due to any lack of inventiveness but simply because they did not need it. As Mr. Cruz pointed out, people write languages, not languages use letters. The concept of using 'j' to represent /j/ is a method of scholarly representation, not a reflection of actual usage in PIE.

In conclusion, Proto-Indo-European did not use the letter 'J' because the letter 'J' was not invented until long after PIE had ceased to be spoken. The language was reconstructed using phonetic symbols and letters that scholars later developed to represent its sounds. Today, we often use the letter 'y' to represent the phoneme /j/ when discussing PIE, but this is a tool for scholarly representation rather than an actual feature of the language.
