Acute accent (´): uses, history, and typographic notes

Functions and meanings

The acute accent serves several distinct roles depending on a language's phonology and orthography. Typical functions include indicating primary stress in a multisyllabic word, marking a particular vowel quality (for example a close versus open vowel), showing vowel length, or denoting a specific tone in tonal languages. In some writing systems the mark contrasts meanings of otherwise identical words. It may influence only pronunciation, or it can be part of the spelling required by morphological or etymological rules.

History and development

Its origin goes back to ancient systems of accentuation, notably the accent marks of Greek, which distinguished pitch patterns in ancient pronunciation. Over centuries the mark evolved into various roles in Romance and other European languages. The same visual sign was adapted into national orthographies with new functions, for instance as a stress marker in modern Spanish dictionaries and as a vowel length marker in Hungarian. Historical development also led to related marks such as the grave and circumflex having complementary uses.

Typographic and computing notes

Typographically the acute can be drawn more upright or more slanted depending on typeface design. It is usually placed above the main part of a letter but may shift slightly right in some fonts. In digital text the acute appears both as part of precomposed characters and as a separate combining diacritic that can be layered onto letters; many keyboard layouts provide dedicated keys or dead-key combinations to type accented characters.

Examples, distinctions, and notable facts

• In Spanish the acute commonly marks stress on a syllable when it deviates from default stress rules (e.g., mamá). See Spanish usage for patterns.
• In French the acute appears only on e (é) to indicate a particular vowel quality; other accents perform different functions.
• Some Slavic and Central European languages use an acute or similar mark to show long vowels or palatalization on consonants (for example Polish ć). For comparative notes consult Slavic and Central European orthographies.

Because its role varies so much from language to language, the acute accent is best understood within the rules of each orthography. Linguists and language learners often rely on dictionaries and style guides to learn when it is required.
