We use a combination of the five senses to understand what is happening around us. If one sense is weak or lacking, we compensate with another sense.

What is the passive voice all about? Sigrid takes us through the basics, step by step. In the active voice, we focus on "who" does something and in the passive voice we focus on "what" someone does.

Although we use the passive tense in the present tense, it's used in other tenses, too, and that's what we look at in this lesson.

Here are some examples of sentences using both the active and passive voices. Different tenses are used, too!

What are causatives? Causal verbs are used to cause things to happen. They're used in causative constructions. Although there are various specific verbs in this category, we commonly use four ordinary verbs for this: ("have," "let," "get," and "make"). Let's make some sense of them.

Now that you have an idea about what causal verbs and causal constructions are, let's give them some context. We're still using the verbs "have," "let," "get," and "make," and the theme is housepainting.

Let's look "under the hood," and see how to build causative constructions using "have," "let," "get," and "make."

Sigrid introduces passive causative constructions, which combine causal verbs and the passive voice. We use them all the time in everyday conversation when we focus on the object rather than the subject.

This segment lays out the building blocks of a passive causative construction. We also compare and contrast causative constructions with other similar constructions. Sigrid uses the expression "to mix and match," which means putting different things together in different ways.

It's time to mix and match the formulas we've talked about. Sigrid mixes and matches them to talk about stuff she can't or doesn't want to do herself. She invites you to do the same.

Every day, we get information from lots of different sources. But how do we know what is true and what is "fake news?" In this 3-part series we explore different kinds of information and misinformation.

What's the difference between disinformation and misinformation? And what about misleading information? Find out in this video.

Audio and video sources can be factual, and can be used as evidence, but they can both be doctored, too. When we don't have the facts, we might have hearsay, but can we trust it?

We can use nouns, verbs, or adjectives to describe someone's personality. Sigrid shows us how to describe someone with a strong personality.

Sigrid introduces her series on English pronunciation and tells us why there isn't always just one "right" way to pronounce words.
