Accent
All words ending in n or s or a vowel are regularly accented on the next to the last syllable; examples, Sausalíto, Altúras, cómen. All others are accented on the last syllable; examples, San Rafael´, Avenal´. In words following the above rules no mark is used, but in the exceptions, which are many, the stress must be indicated by the written accent. Examples, Portolá, Jolón, Álamo, Los Ángeles.
