Even if you\u2019ve grown up speaking English, the words \u201cforth\u201d and \u201cfourth\u201d can be confusing. They\u00a0sound identical\u00a0when spoken and they look similar on paper. To make sure your writing is error free, check out our guide to find out what these words mean and when to use them.\nForth (Out, Away or Onward)\nThe word \u201cforth\u201d is an adverb\u00a0(i.e., it modifies a verb). We use it to show that something is moving out, away, or onward from a point in space or time:\nWe got up at dawn and set\u00a0forth\u00a0for adventure!\nFrom that day\u00a0forth, we vowed to never get up at dawn again.\nThis word is fairly rare in modern English, though you may see it in phrases like those above. Another common use is in\u00a0\u201cback and forth\u201d\u00a0(i.e., moving in one direction and then the opposite one). For instance:\nThe tree swayed back and forth in the wind.\nIn all cases, though, "forth" is related to movement.\nFourth (Number Four in a Sequence)\n\u201cFourth\u201d is an\u00a0ordinal number\u00a0(i.e., it indicates a place in a sequence or rank). We use it when something is number four in a sequence, so it comes after \u201cfirst,\u201d \u201csecond,\u201d and \u201cthird.\u201d For example:\nJustin was proud of coming\u00a0fourth\u00a0in the race.\nIn less formal writing, \u201cfourth\u201d can be shortened to \u201c4th.\u201d However, you should write \u201cfourth\u201d in full when using it in a sentence in formal writing.\n\nFinally, we sometimes use \u201cfourth\u201d to refer to a fraction (i.e., \u00bc ). This is similar to how we say \u201ca fifth\u201d or \u201can eighth.\u201d For instance:\nI spend a fourth of my time correcting spellings.\nThis is less common in British or Australian English, where people call this fraction a \u201cquarter\u201d (like the 25 cent piece, which is \u00bc of a dollar).\n\n[caption id="attachment_15656" align="aligncenter" width="200"] A quarter or a fourth?[\/caption]\n\nIn all cases, though, "fourth" is related to numbers or fractions.\nForth or Fourth?\nThese words sound and look very similar, but try not to get them confused:\n\n \tForth\u00a0is an adverb used to describe moving out or away from a point in space (e.g.,\u00a0We set forth on our journey) or onward from a point in time (e.g.,\u00a0From that day forth). It is always about movement.\n \tWe use\u00a0fourth\u00a0to show that something is number four in a sequence (i.e., it comes after \u201cfirst,\u201d \u201csecond,\u201d and \u201cthird\u201d). It can also be written as \u201c4th\u201d in informal writing. It is always related to the number four.\n\nThe key to telling these terms apart is remembering that \u201cfourth\u201d contains the word \u201cfour.\u201d As such, if you\u2019re looking for a term related to a number, it will always be \u201cfourth.\u201d And don\u2019t forget to have your writing\u00a0checked by a professional\u00a0for complete confidence it is typo free.
