Final answer:
Stress refers to the emphasis placed on certain syllables of a word or words in a sentence, often used in poetry to create rhythm and meter, particularly seen in iambic pentameter.
Step-by-step explanation:
A syllable uttered in a higher pitch or with greater emphasis than others is known as stress. The term stress refers to the prominence given to a particular syllable in a word, or a word within a phrase or sentence, mainly through increased loudness or pitch, which helps to convey meaning and structure in spoken language.
As an important component of language's rhythm, stress is often used in poetry to help establish the poem's meter, which is the rhythmical pattern formed by the arrangement of stressed and unstressed syllables. An example of stress in a metrical foot is seen in iambic pentameter, a common meter in English poetry, where each foot (iamb) consists of an unstressed syllable followed by a stressed syllable.
