ASK A QUESTION what are common Spanish words requiring an accent mark?
when to use accent mark such as que or esta
You can't only learn the common ones because there are thousands of common ones, l recommend that you learn all the words, each with its own accent, and don't forget that some Spanish tenses require accent marks to conjugate them
If you are asking a question with 'que' use an accent.
Almost every word ending in "ón" especially "ción", but there are so many others that you'll just have to get used to it. Once you've practiced Spanish enough you can usually realize which words need accents.
