The built-in purpose of each letter in a language is to represent a specific sound (phoneme) of that language. By combining letters together, we form words, which in turn form sentences and convey meaning.

To understand the purpose of each letter, we need to look at the language's writing system. There are generally two main types of writing systems: phonetic (where letters represent individual sounds) and logographic (where characters represent whole words or ideas).

In a phonetic writing system, each letter represents a specific sound or a combination of sounds. For example, in the English alphabet, the letter "A" usually represents the sound /æ/ as in "cat," while the letter "B" represents the sound /b/ as in "bat." These letters have consistent sounds associated with them across different words.

However, it is important to note that languages may have different spelling conventions or variations, which can make determining the exact sound for each letter more complex. In English, for instance, there are many exceptions and multiple ways to represent the same sound.

To fully understand the purpose of each letter in a specific language, it would be best to consult a linguistic resource, such as a phonetic transcription guide or a guide to that language's writing system. These resources will provide detailed information on how each letter is used and pronounced within the language.
