What role do intonations and stresses play in morphology?

Intonations and stresses are crucial components of spoken language that serve to convey meaning and emotion. They add nuance to communication by indicating emphasis, which can alter the interpretation of a sentence. For instance, a change in intonation can signal a question versus a statement, while stress on certain words can highlight key information or emotion. This affective dimension is essential in how messages are perceived, allowing speakers to express feelings such as urgency, sarcasm, or enthusiasm. Thus, intonations and stresses enrich the spoken form of language, guiding listeners in understanding context and subtext.

This function contrasts sharply with the implications of the other options; syntax rules pertain more to the structural arrangement of words rather than the emotional delivery, while the suggestion that intonations and stresses are insignificant undermines their vital role in effective communication. Additionally, the idea that they only affect written language misunderstands the importance of vocal elements that are inherent to spoken discourse.
