ACCENTS -(á, é, �*, ó, ú, ñ, ü)
if word ends in -n -s or a vowel, the stress falls on next-to-last syllabus.
If you remember that these - está, están, estás - are exceptions, than you remember the rule.
2.
Words with all the other endings have an accent on the last syllabus.
3.
Question and exclamation words - comó, dónde, qué - always have accents.
4.
Demonstrative pronouns have an accent as opposed to demonstrative adjectives.
