These activities are part of our Brazilian Portuguese Grammar series. The skills we are practicing here are covered in our article:

In several Brazilian Portuguese adjectives that contain an o sound in their stem, the o is pronounced differently in the masculine form vs. the feminine form.

  • In the masculine form it is a “closed o” (more like the sound in “ocean”)

  • In the feminine it is an “open o” (more like the sound in “coffee”)

Though this change doesn’t affect the spelling of the adjective stem, it does affect pronunciation. Here is a list of common adjectives that display this change in pronunciation.
