"interdental"的定义和意义

What is "interdental"?

Interdental refers to a type of consonant sound produced by placing the tongue between the upper and lower teeth. This articulation creates a distinct sound that is different from other types of consonants. In English, the primary examples of interdental sounds are the "th" sounds, as in "think" and "this." Interdental sounds are important in phonetics because they add to the variety of speech sounds and play a role in distinguishing words and meanings in a language, contributing to effective communication.
