Expert Opinions on 'daiin'

[Jorge_Stolfi]

In my opinion, "aiin" is a single unit.

I have the same opinion.  And ditto for an, ain, aiiin.  And ditto for aiir, aiis, etc. Besides statistics, there is the air on column 2 of f66r...

As a second opinion, the space following it may very well not be a word break.

I would not agree to that ... my my count, there are too many many lines/labels that end with such sequences:

 46 an   281 ar     8 as 
179 ain   16 air    1 ais 
426 aiin   9 aiir   0 aiis
 20 aiiin  0 aiiir  0 aiiis

In particular there are 163 lines/labels that end with daiin and 40 that end with dain.

I would guess that daiin and ar are just very common words.  dain could be another common word or just a misspelling/mis-transcription of daiin.  The others may well be all noise...

All the best, --jorge
