Questions & Answers about Este casaco grosso é caro, mas eu o comprei com desconto.

Why is este used instead of esse?

Este points to something close to the speaker, while esse refers to something closer to the listener or previously mentioned. Since the speaker is talking about this coat they’re wearing or holding, este casaco is the natural choice.

What does grosso mean here? Doesn’t grosso also mean rude?

When applied to clothing, grosso means thick or heavy (i.e. warm). The sense of “rude” or “coarse” applies more to behavior or style (often as grosseiro). With casaco, it’s purely about the material.

Why is there a comma before mas?

In both Portuguese and English, you separate two independent clauses joined by but/mas with a comma. Here you have
• Este casaco grosso é caro,
• mas eu o comprei com desconto.

What is the o doing in eu o comprei?

The o is a direct-object clitic pronoun standing in for casaco (masculine singular). Eu o comprei literally means “I bought it.”
