The word "suprasegmental" refers to features of speech that extend beyond the level of individual sounds or segments, such as intonation, stress, and rhythm. Antonyms for "suprasegmental" could include "segmental," "phonetic," "linear," or "individual." These terms refer to aspects of language that can be broken down into discrete units, such as individual sounds, syllables, or words. Using these antonyms, we could describe a focus on smaller, more specific aspects of language, rather than the larger-scale patterns and rhythms that are captured by suprasegmental features. However, it's important to remember that both segmental and suprasegmental features are essential components of effective communication.
