Diacritical tildes: tú/tu, él/el, sí/si
Same sound, different word: tú (you)/tu (your), él (he)/el (the), sí (yes)/si (if), sé (I know)/se, dé/de, té/te, más/mas, mí/mi — plus all question words: qué, dónde, cuándo.
pronunciationB1v0.1.0
Explication
The tilde distinguishes stressed words from their unstressed twins: tú tienes tu llave; sí, si querés; sé que se fue. Question/exclamation words keep it even embedded: no sé dónde está.
Post-2010 reform: solo and the demonstrative pronouns (este, ese, aquel) no longer require it; ó between numbers is gone (2 o 3).
Exemples
