select the proper spelling of the word. occurence occurrence

The proper spelling of the word is "occurrence."

The word "occurrence" comes from the verb "occur," which means to happen or take place. When you want to refer to an event or something that takes place, "occurrence" is the noun form of the word. In English, sometimes spelling can be tricky because the same letters may be pronounced differently, or the same sounds can be spelled differently, in different words. Always remember the double 'r' in "occur" stays doubled when you add the suffix '-ence' to make "occurrence." A helpful tip for spelling is to break words down into smaller parts, recalling other words with similar endings or sounds, and to practice writing them out. English spelling requires a lot of memorization, as well as understanding of spelling rules and patterns, so reading widely and practicing frequently are key to improvement.
