One of the distinctive features of Spanish punctuation is the use of inverted exclamation and question marks. This means that an upside-down exclamation or question mark comes at the beginning of a sentence, while there is a regular exclamation or question mark at the end. This helps recognize exclamations and questions immediately, even in longer sentences.
This is especially important in case of questions, as in Spanish the word order of an affirmative sentence and a question is often absolutely the same. Inverted question marks help questions stand out.
Te llamas Marco. – Your name is Marco.
¿Te llamas Marco? – Is your name Marco?
Here are some other features of Spanish punctuation. Depending on your native language, they may be similar to or different from the rules that you are used to.
Another peculiar feature of the Spanish language are vowels marked by acute accents (also called diacritic signs). These are not considered to be separate letters in the Spanish alphabet. They are used in written texts for two main purposes.
The first purpose is to mark word stress if it does not follow the most common pattern (el examen - los exámenes).
The second purpose is to differentiate words that are otherwise spelled absolutely the same, for instance: tú "you" and tu "your," sólo "only" (as in "solamente") and solo "alone".
As you can see, Spanish punctuation marks are mostly visually the same as in other European languages. They even follow many of the same rules. However, when learning Spanish you need to pay special attention to the peculiarities of the Spanish alphabet: the inverted exclamation and question marks, accents placed above the vowels, slightly different use of commas, periods and other punctuation marks.
