To talk about what you are not able to do now, use <span data-no-translation>can&#8217;t<\/span>.<\/strong> These words are modal verbs. They help us express present ability. For example, if you say <span data-no-translation>I can speak English<\/span>, it means you have the skill or knowledge to speak English. If you say <span data-no-translation>I can&#8217;t swim<\/span>, it means you do not have the ability to swim. The structure is simple: <span data-no-translation>Subject + can\/can&#8217;t + the base form of the verb<\/span>. This means the verb after <span data-no-translation>can<\/span> or <span data-no-translation>can&#8217;t<\/span> never changes its form, even for &#8216;he&#8217; or &#8216;she&#8217;. This makes it very easy to use for all subjects (I, you, he, she, it, we, they). You will use <span data-no-translation>can<\/span> and <span data-no-translation>can&#8217;t<\/span> often in daily conversations to describe your skills and capabilities.<\/div>\n<h2>What is &#8216;Can&#8217; for Present Ability?<\/h2>\n<p><span data-no-translation>Can<\/span> is a modal verb.
