Which articulator is considered an active articulator?

• A. The hard palate
• B. The alveolar ridge
• C. The tongue
• D. The teeth

Answer: (C)

An active articulator is defined as a speech organ that moves during the production of speech sounds. The tongue is considered the primary active articulator because it is highly mobile and plays a critical role in shaping various speech sounds. It can change position and shape, making direct contact with other articulators, such as the hard palate, alveolar ridge, or teeth, thereby creating different phonemes.

In contrast, the hard palate, alveolar ridge, and teeth are categorized as passive articulators. They provide a surface against which the active articulators can make contact, but they do not move in producing speech sounds. The hard palate serves as the roof of the mouth, the alveolar ridge is the bony ridge behind the upper teeth, and the teeth can help with the formation of sounds, but it is the tongue that actively manipulates these surfaces to create the range of sounds found in spoken language. Thus, the tongue is rightly identified as the active articulator.
