It's true - the spellings change over time - yet it's a reminder
   that language is primarily a spoken thing and the written words
   are really just an old-fashioned archival format because, well,
   we didn't have audio recording capability for several thousand
   years*tongue emoticon   indeed - and bad handwriting*tongue

   Laziness too. Or getting frilly.
   Like for example, the j being recent to English. Use to be an i.

   Or we lost the long "l" and it got replaced by an "s". I love
   this kind of stuff.   the "great vowel shift" is a cool thing to
   look into as well. It's almost like, en masse, we changed how we
   position our throats, mouths and tongues in how we make vowels.

   maybe one person does it, another follows, and it becomes a fad.

   Witness:

   to say "Breh"*tongue emoticon
