Here's a simple list of common, everyday adjectives in their positive, comparative and superlative forms, divided into groups to facilitate memorization.

Sigrid looks at the comparative and superlative forms of adjectives that have a "Y" or an "E" at the end, and also some that don't follow any pattern at all!

With longer adjectives, we have to add some extra words in order to form the comparative and superlative. Sigrid explains how.

Modal verbs are special verbs that go together with action verbs to indicate ability, permission, obligation and more. Let's see how they work.

Every modal verb is a bit different and not all of them can be used in all tenses. We use "may" for permission, but we can use "can" and its conditional form "could" as well.

When do we use "should" and "could"? At the end of the video, you'll also find a preview of the next 2 videos where modals are used in everyday speech for discussing probability.
