Articulation refers to the clear and precise pronunciation of words and sounds in speech. It involves the movement of the tongue, lips, and other speech organs to produce distinct sounds, making communication more effective. Good articulation helps listeners understand the speaker's message without confusion. In addition to speech, articulation can also describe the way in which different parts of a structure connect and move together, such as in the joints of the human body or in mechanical systems. Proper articulation in these contexts ensures smooth movement and functionality, contributing to overall performance and efficiency.
