How to Build a Modal Verbs Map

Three steps from grammar notes to a map you can revise and test yourself with.

AI builds the map

A modal verb is an auxiliary verb that adds meaning such as ability, permission, obligation or possibility to a main verb. Modals such as can, could, may, might, must, should, will and would do not change form for different subjects and are followed by the base form of the verb. A concept map of modal verbs groups these words by function, so learners can see which modal expresses which idea and how the meaning changes with tense or certainty.

Ability: can and could for present and past skills
Permission: may and can for asking and giving permission
Obligation: must, have to and should for duty and advice
Possibility: might, may and could for uncertain outcomes
Future and polite requests: will, would and shall

Use the map to revise each modal's meaning and sample sentences before a test. To build a version from your own class notes or textbook pages, create a personalized map with CogniGuide.

Modal Verbs Concept Map FAQs

Common questions about modal verbs and how to map them.

What are modal verbs in English?

Modal verbs are auxiliary verbs such as can, must, should and may. They express ability, permission, obligation or possibility, and they take the base form of the main verb without adding endings like -s or -ed.

How do I tell must and should apart?

Must expresses strong obligation or necessity, while should gives advice or a recommendation. A concept map helps by placing each modal under its own meaning branch with example sentences.

Which file types can I use to build my own map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images of your notes. You can also type the topic directly.

Is there a free plan to make a modal verbs map?

Yes, the free plan allows 5 creations a week with no payment needed. Paid plans raise these limits and are available if you need more maps.
