Definition: Phonetics (al) refers to the study of how language sounds are created, interpreted, and used in communication. It is a branch of linguistics that focuses on the structure and function of speech sounds. In phonetics, we deal with sound waves, which include both the loudness and the frequency of each sound. The study of these sounds helps us understand how languages and speech are structured and how they convey meaning through their individual elements (phonemes). Phonetics also includes aspects related to intonation, vowelization, rhythm, and stress. Phonetics can be divided into two main branches: phonology and phonetics. The former deals with the structure of sounds in words, while the latter focuses on the function of these sounds in communication. The term "ally" refers to someone who is very friendly or cooperative. It does not necessarily mean that they are always cheerful or happy, but rather that their behavior is consistent with this characteristic.
