The pronunciation of any Spanish word can be perfectly predicted from its written form.
Spanish is written using the Latin alphabet, with the addition of ñ (eñe). Ch and ll also have their own places in the alphabet (a, b, c, ch, d, ..., l, ll, m, n, ñ, ...). Since 1990, however, words containing the letters ch and ll have been alphabetized as though spelled with the separate letters c - h and l - l.
The letter u sometimes carries diaeresis (ü), and the stressed vowel carries an acute accent (á) in many words.
Exclamatory and interrogative clauses begin with inverted question and exclamation marks.
