For example, <span data-no-translation>She can play the guitar very well<\/span> means she has the skill to do it. To express a lack of ability, you use <span data-no-translation>can&#8217;t<\/span> (or <span data-no-translation>cannot<\/span>), as in <span data-no-translation>He can&#8217;t swim<\/span>, meaning he lacks the skill. When asking about someone&#8217;s ability, you put <span data-no-translation>can<\/span> at the beginning of the question: <span data-no-translation>Can you help me?<\/span> Remember, <span data-no-translation>can<\/span> does not change form for different subjects (e.g., <span data-no-translation>I can<\/span>, <span data-no-translation>she can<\/span>), and you always follow it with the base form of another verb, without &#8216;to&#8217;. This makes it very straightforward to use for B1 learners.<\/div>\n<h2>What Does Can Mean in English?<\/h2>\n<p><span data-no-translation>Can<\/span> is a modal verb. We use <span data-no-translation>can<\/span> to talk about abilities, skills, or possibilities that exist in the present.<\/p>\n<p>It means that someone has the knowledge, skill, or opportunity to do something.<\/p>\n<ul>\n<li><strong>Structure:<\/strong> <span data-no-translation>Subject + can + base form of verb<\/span><\/li>\n<\/ul>\n<div class=\"lc-cta lc-cta-blended\" style=\"border-radius:14px;padding:30px;margin:30px 0;text-align:center;color:#fff;background:linear-gradient(135deg,#0E63C4,#0A2540);\"><h3 style=\"color:#fff;font-size:22px;font-weight:800;margin:0 0 8px;\">&#127891; Learn English with the Blended method<\/h3><p style=\"margin:0 0 10px;opacity:.95;\">Small groups &middot; 24\/7 AI Tutor &middot; Cambridge preparation<\/p><p style=\"margin:0 0 16px;font-size:18px;\">Plans from <strong><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">$<\/span>39<\/bdi><\/span><\/strong> <s style=\"opacity:.6;\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">$<\/span>79<\/bdi><\/span><\/s> per month<\/p><a href=\"\/\" style=\"display:inline-block;margin-top:8px;padding:13px 30px;border-radius:8px;font-weight:700;text-decoration:none;background:#fff;color:#0E63C4;\">Reserve your class<\/a><\/div>\n<h2>How Do We Use Can't?<\/h2>\n<p><span data-no-translation>Can't<\/span> is the negative form of <span data-no-translation>can<\/span>.
