stress: the special prominence that is typically given to one syllable among those that form a word or phrase. Generally the stressed syllable is pronounced louder than the others (with more acoustic energy) and at a higher pitch, and in many languages is slightly longer as well. In some languages, stress can be the only thing that distinguishes two words, in which case it is called phonemic stress. For example, in most varieties of American English, certain minimal pairs consisting of a verb and a noun differ only in stress (such as "permít" and "pérmit"), showing that stress is phonemic in English. In long words or phrases it is common for there to be secondary stresses in addition to the primary stress; primary stress is often written with an acute accent, and secondary stress is sometimes written with a grave accent. Stress is also often called accent [1]; see also ultimate, penultimate and antepenultimate. [Spanish: acento [1]]
