It is spelled with double <em>r<\/em> and double <em>c<\/em>: oc-c-u-r-r-e-d.<\/p>\n<p>The double <em>r<\/em> follows a consistent rule of English orthography: when a verb ends in a single consonant preceded by a single stressed vowel, the final consonant is doubled before suffixes beginning with a vowel (<em>-ed<\/em>, <em>-ing<\/em>, <em>-ence<\/em>).<\/p>\n<p><em>Occur<\/em> ends in <em>-r<\/em>, the preceding vowel is <em>u<\/em>, and that vowel is stressed (the stress falls on the second syllable: oc-CUR). So when adding <em>-ed<\/em> or <em>-ing<\/em>, the <em>r<\/em> doubles:<\/p>\n<p><em>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 occur <\/em><em>\u2192 occurred, occurring, occurrence<\/em><\/p>\n<p>The same rule applies to similar verbs: <em>prefer <\/em><em>\u2192 preferred, preferring<\/em>; <em>refer <\/em><em>\u2192 referred, referring<\/em>; <em>deter <\/em><em>\u2192 deterred, deterring<\/em>; <em>infer <\/em><em>\u2192 inferred, inferring<\/em>.<\/p>\n<p>The double <em>c<\/em> is part of the base spelling of <em>occur<\/em> (not added by the rule) and appears across all forms: <em>occur, occurred, occurring, occurrence<\/em>.<\/p>\n<h1>Common misspellings<\/h1>\n<p>The most frequent errors are:<\/p>\n<p><em><span style=\"text-decoration: line-through;\">occured<\/span><\/em> \u2014 single <em>r<\/em>, missing the doubling rule <em><span style=\"text-decoration: line-through;\">occurence<\/span><\/em> \u2014 single <em>r<\/em> in the noun form <em><span style=\"text-decoration: line-through;\">occuring<\/span><\/em> \u2014 single <em>r<\/em> in the present participle <em><span style=\"text-decoration: line-through;\">occured<\/span><\/em> \u2014 applying the rule but misspelling the base<\/p>\n<p>A useful mnemonic: <em>occur<\/em> has a double letter pair in its base form already (<em>cc<\/em>), and it doubles its final <em>r<\/em> when adding endings.

In academic and professional writing, it is common in scientific and technical contexts because it is more neutral than <em>happen<\/em> and doesn&#8217;t imply an agent:<\/p>\n<p><em>The reaction occurs at temperatures above 60\u00b0C.<\/em><\/p>\n<p><em>Errors of this type occur when the input data is incomplete.<\/em><\/p>\n<p><em>It occurred to the investigators that a confounding variable might be present.<\/em><\/p>\n<p>The third use \u2014 <em>occur to someone<\/em> (to come to mind) \u2014 is distinct from the first two and takes a personal subject indirectly: <em>it occurred to her<\/em> means &#8220;she realized&#8221; or &#8220;the thought came to her.&#8221;<\/p>\n<h1>Occurred vs. happened<\/h1>\n<p><em>Occurred<\/em> and <em>happened<\/em> are largely interchangeable, but <em>occurred<\/em> is somewhat more formal and often preferred in academic and technical writing. <em>Happened<\/em> implies an event in narrative time; <em>occurred<\/em> can describe both events and states or conditions:<\/p>\n<p><em>A significant change occurred in the third quarter.<\/em> (formal, academic)<\/p>\n<p><em>Something happened in the third quarter.<\/em> (more casual, implies narrative)<\/p>\n<p><em>Trinka&#8217;s <\/em><a href=\"https:\/\/www.trinka.ai\/grammar-checker\"><em>g<\/em><\/a><a href=\"https:\/\/www.trinka.ai\/grammar-checker\"><em>rammar checker<\/em><\/a> <em>catches spelling errors in commonly misspelled words like occurred, occurrence, and occurring, and distinguishes them from correct forms in context.<\/em><\/p>\n<h2>References<\/h2>\n<p>Garner, B.
