However, Spanish does have some unique sounds and uses diacritics to represent them. These are the letters that might appear "extra" in Spanish:
* Ñ (eñe): This represents a unique "ny" sound.
* Ch (che): This represents a "ch" sound as in "church".
* Ll (elle): This represents a "y" sound as in "yellow".
These are considered digraphs or combinations of letters that represent unique sounds, not separate letters in the alphabet.
