''The Skill Tree'' lists the skills and example sentences for the fourteen types of skills you're about to learn on Glossika.

When you've completed the sequence of specific sentences, the icon of the skill tree will turn from gray to different colors. Simply click the icon, and you'll get more details about the skill you've learned with.


In this skill, you'll learn how to talk about states (adjectives), being something (predicates), and expressing other acts of speech and thought. Examples:

  • I am/feel good.

  • The book is heavy.

  • I speak English.

  • I am a teacher.

  • I am at school.


In this skill, you'll learn how to say that something exists and to show possession. Examples:

  • there's a tree / there was a tree

  • there are trees / there were trees

  • He has a car.

  • He has a sister.

  • A car has four wheels.


This skill covers how to discuss movement to or from a location.

  • I ride a bus to work.

  • He's walking home from class.

  • An athlete runs toward the finish line.


This skill includes a large number of verbs that change the state of an object. Causative verbs also act upon or request other people to do (or become) something.

  • Close the door, please. --> causes the door to become closed

  • Increase the volume. --> causes the volume to increase

  • Buy this! --> causes money to be spent


This skill includes verbs of motion and other actions.

  • Stand up.

  • I kicked a ball.

  • I eat an apple every day.


This skill covers how to discuss quantities and amounts.

  • There are five books on the table.

  • The book costs fifty dollars.

  • That's a lot of money to spend on a fork.


Now let's take everything you've learned so far and practice how to say them in the negative!

  • don't/doesn't do (verb negation)

  • never do (adverb negation)

  • do nothing (object negation)

Complex Verbs

With this skill, you'll learn to use the potential mood to discuss whether something is possible and/or likely to occur. You'll learn phrases like:

  • I can/will do

  • I could/should/would do

  • I may/must/might do

  • I need/have/supposed to do

Timed Actions

Here, you'll learn to communicate more nuanced notions of time and to compare the time between events. You'll learn phrases like:

  • about to do

  • just did

  • keep/continue doing


With this skill, you'll add additional arguments to verbs โ€” potentially whole clauses. Arguments help to flesh out the meaning of a verb in particular sentence and include things like subjects (who does an action), direct objects (what receives the verbs action), and indirect objects (to or for whom an action is done.)

  • help somebody to X

  • give X to somebody

  • He and I often go running together.

  • We see/meet each other.

Complex Causative

In this skill, you'll learn to communicate more nuanced causative ideas, such as attempts to do/avoid doing something.

  • try/fail to do

  • succeed at doing

  • avoid doing

  • make/have somebody do something

Complex Time

In this skill, you'll learn to express more nuances of time, such as communicating that you've had an experience or clarifying the starting and stopping points of an action.

  • do one thing after/before another

  • do something again and again

  • do something while doing something else

  • be doing something X when something Y happened

  • start/finish/stop doing

  • to have done something before


In this skill, you'll learn various nuances of evidentiality:

  • It was supposed to have happened.

  • It seems to have happened.

  • It must have happened


Many actions are done for a reason, or perhaps in spite of one. You'll learn about that sort of stuff here. These generally tend to be longer sentences, and include things like:

  • whether or not something happened

  • the reason why something happened

  • because something happened
