Dear chibolts,
I am interested in examining patterns in CDS for words of different parts of speech, and I am hoping to be able to use the %mor line from CHILDES corpora for this analysis. I am running my analyses in R, using regular expressions to identify the part of speech for each word, which is working very well (thank you for making these excellent corpora available!). I am having trouble interpreting some of the MOR codes, however. 
Is there a complete list anywhere giving the definitions of the MOR codes? 
I was able to find several informative posts on this topic (https://groups.google.com/d/msg/chibolts/5N8m43WrCZs/jSkHAm6aSY8J, https://groups.google.com/d/msg/chibolts/mLxcw2qyPpk/-wOqnUhh3HgJhttps://groups.google.com/d/msg/chibolts/zAevVn1HUoU/ULg-ub4iBAAJ), but none actually provide a complete list of definitions of MOR tags for English. The CHAT manual provides definitions and examples for common codes (Table 45 p.114, and Table 50 p.118) but omits many less common codes, and the article linked at the top of the MOR grammars page is helpful in terms of understanding how MOR works but does not define the MOR codes themselves except as examples. I have also examined the English mor files, as Leonid and Brian have recommended, and while this yields a (nearly) complete list of the codes, I couldn't find anything like definitions of each. Many are obvious (n is noun, v is verb, det is determiner) but I'd like to be able to check a few (e.g. n:pt, meta, bq, cm). 
Thanks in advance for your help, and for maintaining this fantastic resource!
Cheers,
Rose

Dear Rose,

This information was implicit in the big table on pages 175 and 176 of the CLAN manual, but to make it more explicit, I added a column listing the part of speech used by each lexicon file.  And I also added some important material to the paragraph just before the table to describe features coming from the 0affix.cut, sf.cut and punct.cut files.

Also to make that table correspond to the actual files, I divided up a couple.  So, please get a new copy of the manual and of ENG and hopefully all of this will be clear.
