Here’s a mystery: I have a lexical rule A which is input to another lexical rule B. Lexical rule A has two instances which do not differ in anything but their orthography:
when I use the first instance, I get a parse. When I use the other with the same rest of the word, I don’t. I double checked all the characters (in fact I copied and pasted the affix from the test suite into the choices file; there was no file diff):
What else can it be?? I think I can just replace the affix that doesn’t work with the one that works in my test suite, but… what could be going on?
