Á

Á (Latin Capital Letter A with Acute, U+00C1) is an uppercase Latin letter formed by combining the standard 'A' with an acute accent mark (a small diagonal line slanting upwards from left to right) positioned above it. This character is indispensable across numerous languages, including Spanish, Portuguese, Czech, Slovak, Hungarian, and Irish, where it primarily serves to indicate a stressed syllable, a long vowel sound, or to differentiate between words that would otherwise be homographs (e.g., in Spanish, 'está' (it is) vs. 'esta' (this)). Historically, the acute accent's origins trace back to ancient Greek prosody for marking rising pitch. Its lowercase form is 'á' (U+00E1), and it belongs to a broader family of Latin letters featuring various diacritics, all crucial for accurate pronunciation and meaning in their respective languages.
