Estou pensando

You can use it alone or with the preposition em. For example, Estou pensando em você means "I am thinking of you." If you are weighing an action, use em plus a verb. Estou pensando em viajar means "I am thinking about traveling." It is incredibly flexible and grammatically simple.

Use it at a restaurant when the waiter is hovering. Use it during a meeting when a colleague asks for your opinion. It works great in text messages when someone asks for a favor. It signals that you are taking the request seriously. It sounds much better than a blank stare or a long "uhhh."

Don't use it for things that require an immediate, instinctive reaction. If someone asks if you like their new haircut, don't say Estou pensando. That silence is dangerous! Avoid it when a simple "yes" or "no" is expected for safety. Also, don't use it if you've already made up your mind. It can sound indecisive if overused for small things.

Brazilians and Portuguese people value social harmony. Saying Estou pensando is a polite way to avoid saying "no" immediately. It softens the blow of a potential rejection. It shows you are a thoughtful person who weighs options. In a fast-paced world, this phrase is a small island of calm.

In Brazil, you will often hear Tô pensando. This is the shortened, more casual version of Estou. In Portugal, you might hear Estou a pensar. Both mean the exact same thing. You can also add ainda (still) to say Ainda estou pensando. This emphasizes that the decision-making process is taking a while.
