Over the weekend I have pored over the list of most common words.
  They can be gruped into the following major sets, based on prefixes:
  
    qoljc*/qoqjc*
    
    cccc*/csccc*
    
    oljc*/oqjc*
    
    cgc*
    
    ixcccc*/ixcsccc*
    
    cccljc*/csccljc*/cccqjc*
    
  plus the following short connectives:
  
    oix qoix ois csoix oixcg ixoix
    
    csciiiu csciiiiu ciiiiu
    
  To confirm some hunches about gallows, I tabulated all \lj/ and \qj/
  gallows letters and their neighboring \c/ strings:
  
   cat bio-j-jsa-gut.wds \
      | sed -e 's/cs/c/g' \
      | enum-contexts -vPAT='c*qjc*' -vLCTX=0 -vRCTX=1 \
      | wfreq \
      > .foo
   
    cat bio-j-jsa-gut.wds \
      | sed -e 's/cs/c/g' \
      | enum-contexts -vPAT='c*ljc*' -vLCTX=0 -vRCTX=1 \
      | wfreq \
      > .bar
      
    pr -m -s'   ' -t -i' '1 .foo .bar > .baz


      \qj/ gallows              \lj/ gallows

  Now let's check the significance of the \s/ plume on \c/.
  First, let's list all initial \c/-strings that have plumes
  against all that don't have them:
  
  
    cat bio-j-jsa-gut.wds \

          -e 's/cs/z/g' \
          -e 's/^/_/g' \
          -e 's/$/_/g' \
      | enum-contexts -vPAT='_c*z[zc]*[^zc]' -vLCTX=0 -vRCTX=0 \
      | wfreq \
      > .foo
   
    cat bio-j-jsa-gut.wds \
      | sed \
          -e 's/cs/z/g' \
          -e 's/^/_/g' \

  Some conclusions:
  
    * The gallows characters \qj/ and \lj/ appear to be closely related:
      for every common word with \lj/, there appears to be a 
      a word with \qj/ that occurs with about 1/4 the frequency.
      
    * The same phenomenon can be noted with respect to prefixes
      containing \cc/ and \csc/: for every word beginning with \cc/,
      there is a word where the first \cc/ is replaced by \csc/,
      and practically the same frequency.
      
    * There apepars to be much confusion between the suffixes \iu/
      and \iiiu/. 
      
    * There appears to be much confusions between \o/ and \ci/
      
  Recall also our previous guess that \cy/ is just the final form of
  \ci/.  Therefore, I have decided to do the following simplifications
  before recomputing the consensus file:
  
    * Ignore, for the time being, the difference between \qj/
      and \lj/, and between \qg/ and \lg/, replacing them
      by \h/ and \p/, respectively;
    
    * omit the \s/ plume after \c/;
    
    * replace all strings \iiu/, \iiiu/, \iiiiu/, etc. by \m/
    
    * replace \cy/ by \ci/.
    
    * replace \o/ by \ci/
    
  Needless to say, I don't mean that these differences are meaningless;
  it is just that there seems to be structure to be discovered that 
  does not depend on these features.

  It seems that the gallows letters transected by \c..c/ are distinct letters. 
  To check that, let's look at the distribution of \c/ strings on their own
  and around the \lj/ and \qj/ gallows, ignoring the \s/ plumes on \c/:
