English uses diacritical marks almost solely in words of foreign origin, and they are often omitted. Examples of English words using diacritical marks are "façade" (which uses a cedilla), "résumé" (two accent marks), "naïve" (umlaut) and "piñata" (tilde).
Spanish uses three types of diacritical marks:
- The tilde is used to distinguish n from ñ. In a technical sense, this might not be considered a diacritical mark, since n and ñ are separate letters of the alphabet.
- Accent marks are used as an aid in pronunciation and also to distinguish some sets of words that are otherwise spelled alike and pronounced alike but have different meanings or different grammatical usages.
- The umlaut, often called a dieresis, which is placed over the u when it is pronounced after a g in the combinations güe and güi. Umlauts are rarer than the other types of diacritical marks.
