For example, if you say <span data-no-translation>I went to the shop to buy milk<\/span>, the phrase <span data-no-translation>to buy milk<\/span> explains *why* you went to the shop. This grammar point is very common in everyday English and helps you communicate your intentions clearly. It&#8217;s like answering the question &#8220;Why?&#8221; for an action. You might go to a cafe <span data-no-translation>to meet friends<\/span>, or study hard <span data-no-translation>to pass an exam<\/span>. It helps connect two ideas: the action you take and the reason for that action. This structure is essential for A2 learners to express their intentions and purposes simply and effectively. Mastering this will make your English sound more natural and precise, improving your ability to describe daily activities and plans.<\/div>\n<h2>What is the Infinitive of Purpose?<\/h2>\n<p>The infinitive of purpose is a grammar structure that explains the *reason* or *goal* behind an action. It answers the question &#8220;Why?&#8221;<\/p>\n<ul>\n<li>We form it with <span data-no-translation>to<\/span> followed by the <span data-no-translation>base form of a verb<\/span>.<\/li>\n<li>For example, if you ask <span data-no-translation>Why did you call me?<\/span>, the answer could be <span data-no-translation>I called you to ask about the party.<\/span> Here, <span data-no-translation>to ask<\/span> is the infinitive of purpose.<\/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 Use the Infinitive of Purpose?<\/h2>\n<p>We use this structure to show the intention or aim of an action. It often follows verbs that describe movement or activity.<\/p>\n<ul>\n<li>You can use it after verbs like <span data-no-translation>go<\/span>, <span data-no-translation>come<\/span>, <span data-no-translation>travel<\/span>, <span data-no-translation>study<\/span>, <span data-no-translation>call<\/span>, <span data-no-translation>buy<\/span>, and many others.<\/li>\n<li>Think of it as explaining the *purpose* of the main verb in the sentence.<\/li>\n<li>For instance, <span data-no-translation>She went to the library to borrow a book.<\/span> (<span data-no-translation>to borrow a book<\/span> is the reason she went).<\/li>\n<\/ul>\n<h2>Infinitive of Purpose vs. Other Uses of 'To'<\/h2>\n<p>The word <span data-no-translation>to<\/span> has many uses in English. It can be a preposition or part of an infinitive verb.<\/p>\n<ul>\n<li>When <span data-no-translation>to<\/span> is followed by the base form of a verb and explains *why* something happens, it is the infinitive of purpose.<\/li>\n<li>Example: <span data-no-translation>I study English to get a better job.<\/span> (Purpose)<\/li>\n<li>Be careful not to confuse it with <span data-no-translation>to<\/span> as a preposition, like in <span data-no-translation>I go to school<\/span> (here <span data-no-translation>school<\/span> is a noun).<\/li>\n<li>Also, some verbs are followed by <span data-no-translation>to + infinitive<\/span> as part of their structure, like <span data-no-translation>I want to learn<\/span>. This is not always purpose. The key is asking \"Why?\".<\/li>\n<\/ul>\n<table>\n<caption>Comparing &#x27;To&#x27; for Purpose and &#x27;For&#x27; for Purpose<\/caption>\n<thead>\n<tr>\n<th>Structure<\/th>\n<th>What it explains<\/th>\n<th>Example<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-no-translation>To + base verb<\/span><\/td>\n<td><span data-no-translation>The reason for an action<\/span><\/td>\n<td><span data-no-translation>I went to the library to study.<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-no-translation>For + noun<\/span><\/td>\n<td><span data-no-translation>The purpose of an object or thing<\/span><\/td>\n<td><span data-no-translation>This machine is for making coffee.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Examples<\/h2>\n<ul>\n<li><span data-no-translation>I went to the supermarket to buy some fruit.<\/span><\/li>\n<li><span data-no-translation>She called her friend to invite her to the party.<\/span><\/li>\n<li><span data-no-translation>He studies hard to pass his exams.<\/span><\/li>\n<li><span data-no-translation>They traveled to Spain to learn Spanish.<\/span><\/li>\n<li><span data-no-translation>We stopped the car to take a picture.<\/span><\/li>\n<\/ul>\n<h2>Practice<\/h2>\n<div class=\"h5p-iframe-wrapper\"><iframe id=\"h5p-iframe-1600\" class=\"h5p-iframe\" data-content-id=\"1600\" style=\"height:1px\" src=\"about:blank\" frameBorder=\"0\" scrolling=\"no\" title=\"KET05 L1 GRAMMAR Infinitive of purpose\"><\/iframe><\/div>\n<div class=\"lc-cta lc-cta-exam\" style=\"border-radius:14px;padding:30px;margin:30px 0;text-align:center;color:#fff;background:#0A2540;\"><h3 style=\"color:#F2B705;font-size:22px;font-weight:800;margin:0 0 8px;\">Ready to earn your certificate?<\/h3><p style=\"margin:0 0 16px;opacity:.92;\">Langcom prepares students for Cambridge, IELTS, TOEFL, DELE, SIELE and Michigan exams.<\/p><a href=\"\/\" style=\"display:inline-block;margin-top:8px;padding:13px 30px;border-radius:8px;font-weight:700;text-decoration:none;background:#F2B705;color:#0A2540;\">Get started with Langcom<\/a><\/div>\n<h2>Common mistakes for Spanish speakers<\/h2>\n<p>Spanish speakers often make a common mistake by using <span data-no-translation>for + -ing<\/span> or <span data-no-translation>for + noun<\/span> when they mean purpose with a verb.<\/p>\n<ul>\n<li><strong>Incorrect:<\/strong> <span data-no-translation>I went to the library for studying.<\/span><\/li>\n<li><strong>Correct:<\/strong> <span data-no-translation>I went to the library to study.<\/span><\/li>\n<li><strong>Incorrect:<\/strong> <span data-no-translation>She bought a new phone for calls.<\/span> (While <span data-no-translation>for calls<\/span> is grammatically possible, <span data-no-translation>to make calls<\/span> is the common way to express purpose with a verb.)<\/li>\n<li><strong>Correct:<\/strong> <span data-no-translation>She bought a new phone to make calls.<\/span><\/li>\n<\/ul>\n<p>Remember, for purpose with a verb, always use <span data-no-translation>to + base form of the verb<\/span>.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What is the infinitive of purpose?<\/h3>\n<p>It is a grammar structure using <span data-no-translation>to + the base form of a verb<\/span>.
