The linguistic feature that encompasses intonation, tone, stress, and rhythm…

In linguistics, suprasegmental features are properties of speech that extend over more than a single sound segment. They include intonation (the rise and fall of pitch), tone, stress (emphasis on particular syllables), and rhythm (the timing pattern of speech). The term that collectively names these features is prosody.

The question names exactly these four properties, intonation, tone, stress, and rhythm, so together they define prosody.

Why the other options do not fit:

• Poetry names a literary genre that can employ rhythmic and rhyming devices, not the linguistic term for these speech features themselves.

• Phonetics is the broader branch of linguistics that studies how individual speech sounds are produced and perceived; prosody is the specific term for the intonation, tone, stress, and rhythm pattern that phonetics can describe but does not itself name as a single concept.

• Pragmatics is the branch of linguistics that studies how context and social use shape meaning; although prosody can carry pragmatic effects such as emphasis or implied stance, it is prosody, not pragmatics, that specifically names the intonation, tone, stress, and rhythm pattern in the question.

Hence, prosody is the term for intonation, tone, stress, and rhythm in speech.
