What are some common mistakes made by Spanish learners when it comes to the use of accents and diacritical marks?

Accents and diacritical marks are an important part of the Spanish language, as they can change the meaning of a word. However, many Spanish learners struggle with using them correctly. Here are some common mistakes:

• Not using accents on words that require them: Spanish words that end in a vowel, n, or s are stressed on the next-to-last syllable unless marked otherwise with an accent mark. For example, the word 'camino' (road) is pronounced 'CA-mi-no,' while 'caminó' (walked) is pronounced 'ca-mi-NÓ.'
• Using accents on words that don't require them: Some Spanish learners use accents on words that don't require them. For example, 'más' (more) and 'mas' (but) are two different words with different meanings, but only 'más' requires an accent mark.
• Confusing diacritical marks: Spanish learners may also confuse diacritical marks, such as the tilde (~) and the diaeresis (¨). The tilde is used on the letter 'ñ' to indicate a different sound, as in 'mañana' (tomorrow). The diaeresis is used to indicate that two vowels should be pronounced separately, as in 'pingüino' (penguin).

To avoid these mistakes, Spanish learners should practice using accents and diacritical marks consistently, paying attention to the rules and seeking feedback from native speakers.
