I created my first language by starting with a phonology and word
generator. This is not the way to go. (Actually, it wasn't so much a
language as bunch of words. It didn't even have a real grammar until just
before I put it to bed for ever (and I don't mean it was an English
rip-off; it even looked up to that).) Words, imho, should come last, if at all.

For my more recent ones, I worked out (in this order) a phonology,
phonological history, various parts of the grammar (and history), words
(and history). The grammars are still being worked on tho. I don't even
know if it's really possible to have one finished. And they have very few
words, almost always created under duress (that is, during relays).

How to languages without the applicable articles make the distinction?
