Questions & Answers about A cadeira é menos pesada do que a mesa.
Why do we use do que here instead of just que for "than"?
In Portuguese, when comparing two things, "than" usually translates to do que. You can actually drop the do and just say que (like menos pesada que a mesa), but do que is very common and sounds perfectly natural in Portugal.
Why is it pesada instead of pesado? Does it match the chair or the table?
What if we compared the feminine chair to a masculine object, like o sofá (the sofa)?
Why do we use é (from the verb ser) instead of está (from estar)?
