It shows that there is a rule, a law, or an external situation that makes an action required. For example, <span data-no-translation>I have to wear a uniform at work<\/span> means it&#8217;s a rule from your employer. We use <span data-no-translation>have to<\/span> when the obligation comes from outside the speaker. When something is <strong>not necessary<\/strong>, we use <strong><span data-no-translation>don&#8217;t have to<\/span><\/strong> or <strong><span data-no-translation>doesn&#8217;t have to<\/span><\/strong>. For instance, <span data-no-translation>You don&#8217;t have to work on Sundays<\/span> means it&#8217;s optional. This is different from <span data-no-translation>mustn&#8217;t<\/span>, which means something is forbidden. Think of <span data-no-translation>have to<\/span> as similar to &#8220;tener que&#8221; in Spanish. It&#8217;s important to remember that <span data-no-translation>have to<\/span> uses <span data-no-translation>do<\/span> or <span data-no-translation>does<\/span> for questions and negative sentences, just like regular verbs, not like typical modal verbs. This makes its structure unique.<\/div>\n<h2>What Does &#8216;Have to&#8217; Mean?<\/h2>\n<p><span data-no-translation>Have to<\/span> means that something is necessary. It shows an obligation, often because of a rule, a law, or a situation.<\/p>\n<p>This obligation usually comes from outside the speaker. It&#8217;s not a personal feeling, but something required by others or circumstances.<\/p>\n<ul>\n<li>For example, <span data-no-translation>Students have to study for exams.<\/span> (This is a rule from the school.)<\/li>\n<li>Another example: <span data-no-translation>I have to go to work early tomorrow.<\/span> (This is an obligation from your job.)<\/li>\n<\/ul>\n<div class=\"lc-cta lc-cta-placement\" style=\"border-radius:14px;padding:30px;margin:30px 0;text-align:center;color:#fff;background:linear-gradient(135deg,#2B87DA,#29C4A9);\"><h3 style=\"color:#fff;font-size:22px;font-weight:800;margin:0 0 8px;\">&#9997;&#65039; Not sure which level you are?<\/h3><p style=\"margin:0 0 16px;opacity:.95;\">Take our free placement test and get personalized feedback from certified Cambridge examiners.<\/p><a href=\"\/english\/academy\/free-test\/\" style=\"display:inline-block;margin-top:8px;padding:13px 30px;border-radius:8px;font-weight:700;text-decoration:none;background:#0A2540;color:#fff;\">Take our FREE Placement Test<\/a><\/div>\n<h2>How Do We Form 'Have to'?<\/h2>\n<p>The structure of <span data-no-translation>have to<\/span> changes depending on the subject and whether it's positive, negative, or a question.<\/p>\n<h3>Positive Sentences<\/h3>\n<ul>\n<li>For <span data-no-translation>I, You, We, They<\/span>, use <span data-no-translation>have to + base verb<\/span>.<\/li>\n<\/ul>\n<p>Example: <span data-no-translation>We have to finish this report today.<\/span><\/p>\n<ul>\n<li>For <span data-no-translation>He, She, It<\/span>, use <span data-no-translation>has to + base verb<\/span>.<\/li>\n<\/ul>\n<p>Example: <span data-no-translation>She has to wake up early for her flight.<\/span><\/p>\n<h3>Negative Sentences<\/h3>\n<p>To say something is not necessary, we use <span data-no-translation>don't have to<\/span> or <span data-no-translation>doesn't have to<\/span>.<\/p>\n<ul>\n<li>For <span data-no-translation>I, You, We, They<\/span>, use <span data-no-translation>don't have to + base verb<\/span>.<\/li>\n<\/ul>\n<p>Example: <span data-no-translation>You don't have to pay for this.
