How does phonetics differ from phonology. Use relevant examples. ?

Phonetics and phonology are two subfields of linguistics that study different aspects of speech sounds. Phonetics focuses on the physical properties of speech sounds, while phonology examines the way sounds function within a particular language system.

Phonetics deals with the production, transmission, and perception of speech sounds. It analyzes the physical characteristics of sounds, such as their articulation (how they are produced by the vocal organs), acoustic properties (how they are transmitted as waves through the air), and auditory perception (how they are perceived by the human ear). For example, phonetics would study the difference between the English "p" sound in "pat" and the "b" sound in "bat," examining the specific articulatory movements and acoustic properties that distinguish them.

On the other hand, phonology focuses on the systematic organization of speech sounds within a particular language or languages. It investigates the patterns and rules that govern how sounds function and interact with each other in a given language. Phonology is concerned with phonemes, which are the smallest units of sound that can distinguish meaning in a language. For instance, in English, the sounds /p/ and /b/ are considered distinct phonemes because they can change the meaning of words, as in "pat" and "bat." Phonology would analyze the rules that determine when each phoneme is used and how they can be combined to form words and sentences.

In summary, phonetics examines the physical properties of speech sounds, while phonology studies the abstract patterns and rules governing the organization of sounds within a language.
