Questions & Answers about Los sofás no son pequeños.
Wait, shouldn't words ending in "a" be feminine? Why is it los sofás instead of las sofás?
Since sofá ends in "a", shouldn't the adjective be pequeñas?
Why does sofás have an accent mark on the "a"?
The accent mark tells you to emphasize the final syllable (so-FA). Without it, the natural pronunciation rule in Spanish would make you stress the second-to-last syllable (SO-fa) because the word ends in an -s.
