Determining When to Use "Que" vs. "do Que"

I am wondering if there are any rules that determine when to use “que” or “do que” when comparing things. This is puzzling me. I am just going through adjectives in Lesson 4, I think, and I am having trouble determining when to use which. When is it that one has to use “do que” rather than just “que”?
Just a facetious example: “Uma mosca é mais pequena que um elefante!” or “Uma mosca é mais pequena do que um elefante!” Some of the examples in Lesson 4 Adjectives seem like either one would be correct, and yet only one form is shown as correct. :slightly_smiling_face:

Both are correct! “Do que” only becomes more recommended than the alternative (without necessarily being the only acceptable option) if the second part of the comparison includes a verb.

  • Tu falas mais do que ouves. (You talk more than you listen)
  • Ele é mais inteligente do que pensa. (He’s more intelligent than he thinks)

Otherwise, anything goes:

  • Ela é mais alta que/do que a irmã. (She’s taller than her sister)
  • Eu sou melhor que/do que ele. (I’m better than him)

For specific questions/concerns related to the website, you can send me a message here or support ticket via the usual channel and I’ll look into it :slight_smile:
