19. Is your conlang a priori (devised from scratch) or a posteriori (based on a specific natural language or language family), or a mix of a priori and a posteriori elements?

a priori	24	46.15%
a posteriori	17	32.69%
mixed	11	21.15%

20. Describe the typology of your conlang - what is its primary word order (SVO, SOV, VSO...; pre- or postpositional; etc.)? Is it isolating, agglutinating, fusional, polysynthetic? Is its case or word order system primarily accusative, ergative, active, other...?

I summarized people's variegated responses to this in four fields:

21. a. How extensive or complete do you consider your conlang to be (in grammar and vocabulary)?

Based on people's widely varying responses to this, I came up with percentages of completion for vocabulary and grammar. Some respondents estimated the percentage completion of each portion; most used general terms like "fairly complete" or "not very complete", etc., or described the language's capabilities and limitations. 24 respondents mentioned the number of words in their conlang's lexicon; it's interesting to note the lack of strong correlation between how complete a conlanger considers their language to be and how large its vocabulary is. For instance, one describes its vocabulary as "extensive" at 1000 words, and another describes it as "not very complete" at over 2500 words. How expressive a language can be with a given lexicon size depends, of course, to a great extent on its derivational morphology, and to some extent on its semantics, how large a range of meanings are expressed by a typical conlang word.

average of field 21a_grammar : 82.47 with 44 numeric values
minimum value: 5
maximum value: 100

average of field 21a_vocab_pct : 58.86 with 46 numeric values
minimum value: 5
maximum value: 100

average of field 21a_vocab_count : 3173.42 with 24 numeric values
minimum value: 120
maximum value: 13027

21. b. If you are not yet fluent in it, do you consider the language complete enough for fluency to be attainable, or would it need considerably more development for that to be possible?

yes	30	57.69%
no	20	38.46%
(no response)	2	3.85%

22. Does your conlang have features that might be expected to make it especially difficult for speakers of your native language?

yes	31	59.62%
no	20	38.46%
(no response)	1	1.92%

23. Does your conlang have possibly unnatural features that might be expected to make fluency difficult or impossible for humans?

no	47	90.38%
(no response)	3	5.77%
yes	1	1.92%
maybe	1	1.92%

no	21	40.38%
