Questions & Answers about Hay algún error en el documento.
Why is it algún instead of alguno?
Algún is a shortened form of alguno. We drop the -o and add a written accent when it comes directly before a masculine singular noun, like error.
Why does algún have an accent mark?
When we drop the -o from alguno, the spoken stress stays on that final syllable (-gun). To keep the pronunciation correct according to Spanish spelling rules for words ending in the letter 'n', we must add a written accent over the u.
Could algún translate to 'any' as well as 'some'?
Yes! While the translation here says 'some mistake', algún is also used for 'any' in questions or uncertain statements. For example, if this were a question (¿Hay algún error?), it would mean 'Is there any mistake?'.
How do we know to use the masculine form algún and not the feminine alguna?
The word error is a masculine singular noun in Spanish. If the noun were feminine, like duda (doubt), we would use the full feminine form without dropping any letters: alguna duda (some doubt).
