I am not a native speaker, and I find it very interesting that night is written with gh. Why is it spelled this way?

  • As opposed to "nite"? Commented Jan 26, 2014 at 0:52

    And why "eight," "bight", "blight", "fight," "sight", "flight", "might," "weight," "freight," etc? Commented Jan 26, 2014 at 1:02
  • Between i and t? Commented Jan 26, 2014 at 1:04

    It's the way it used to be spelled but pronunciation has changed.

  • As opposed to "nite"? yeah "rite"! Same question was asked by Ser Davos in Mhysa (S3E10) - Game of Thrones. Commented Jan 5, 2019 at 14:50

When you see a GH spelling in English and it's silent or not pronounced like G, you're dealing with Middle English. That's the language for which English spelling was developed.

Middle English had an /h/ phoneme, and it occurred both

  • pronounced [h] before vowels
    (where /h/ occurs in Modern English: Ha he who huh hey /ha hi hu hə he/)


  • pronounced [x] (rather like German CH or Russian Х or Hebrew ח) after vowels.
    It was spelled GH in those cases, because it was pronounced [x], instead of [h].

Part of the change from Middle to Modern English was that the postvocalic [x] allophone of /h/ either disappeared (as in night), or mutated to another fricative, like [f] in enough or trough.

Once these had disappeared (leaving only fossils in the spelling), the prevocalic allophones, having no other H-like sounds to contrast with, mutated into the current bevy of voiceless vocal onsets.

    How was it pronounced? In broad Scots they say something like 'It's a bricht, moonlicht nicht! was it like that?

    @WS2 At 03.24 you can hear a text being read out in Middle English, and yes, it does rather sound like Scottish. It's quite fascinating stuff. youtube.com/watch?v=GrnXgVTTrCI&list=PL60EDCEF24DB56379

    Could I add that in my native East Yorkshire, there is a (sort of) remnant of the now-silent /x/. In this speech, so-called long A is a more-or-less pure vowel, so 'late' is pronounced /leːt/. This is true for all long As except in some words with silent 'gh': 'eight' is pronounced /ɛɪt/, 'weight' is pronounced /wɛɪt/ [so 'weight' and 'wait' don't rhyme]. This diphthong occurs only in this small group of words where /x/ disappeared, Commented May 25, 2016 at 8:28

    @JohnLawler Thanks for that, and for awakening a 50-year-old memory of a French teacher explaining the 'circonflex'. I guess 'Compensatory Lengthening' applies to the non-rhotic pronunciation of [e.g.] 'cart'? Commented Apr 5, 2017 at 11:01
