Questions & Answers about Esta mobília é escura e pesada.
Why do we use é here instead of está?
Why do the adjectives end in "-a" (escura, pesada) instead of "-o"?
In Portuguese, adjectives must match the gender of the noun they describe. Because mobília is a feminine noun, the adjectives for dark (escura) and heavy (pesada) must also take their feminine forms.
Why is the word for "this" Esta instead of Este or Isto?
Is mobília treated differently than the English word "furniture"?
Yes! In English, "furniture" is generally uncountable (we say "a piece of furniture"). In Portuguese, mobília is a regular countable noun. While it is used in the singular here to describe a collective set of furniture in a room, you can also make it plural (mobílias) if you are talking about multiple distinct sets of furniture.
