I would reduce the number of roots to 222;
eliminate all diacritics in writing;
eliminate all words containing the sound L;
eliminate all letters of dubious phonetic value except x pronounced as in IPA;
use only one source of vocabulary, choosing internationally known words as much as practicable and approaching the ProtoHuman language as much as practicable;
eliminate compounding except for 3 words that can be attached as suffixes; otherwise, words combine by simply putting one after the other; for the beginners, hyphens can be added;
use only 5 basic suffixes, to show the part of speech: -o for nouns, -a for adverbs, -i for active verbs, -eti for passive verbs, and silencing the –i to make imperative, or, what is known in Esperanto as jussive;
these basic suffixes can be added on already suffixed words;
no marker for adjectives: all nouns put before the head noun work as adjectives;
have 4 prefixes for yes / no functions, and 13 suffixes rather rare, but always available for derivation;
mark the object only if not following the verb or subject;
omit the verb subject if it can be inferred, or if it is general (like German “Man” and French “on”);
allow everything to be omitted if it can be inferred;
have 3 simple infixes, rarely used but available to show the person of a word;
allow, on the highest level, a possibility of rare backward formation for a more concise way of derivation;
have a possibility for both prepositional and postpositional usage too, in speech indicated through emphasis, intonation, speech division, and, in writing, punctuation.
ALL THESE HAS ALREADY BEEN DONE, and the result is SostiMatiko ( http://konlangerz.com/conlang/7/Systema ... ostimatiko
). Actually, SostiMatiko was born in almost complete ignorance of Esperanto; recently i had a look to Esperanto, and i found it shares some characteristics and some way of thinking. However, SostiMatiko is much more simple, much more free, all its material is contained on one A4 size page (written with big size fonts (size 16 to 20) and ample spaces), all its material can be learned within just one day, and still it can express everything that Esperanto can. Also, SostiMatiko is great for exercise and for fun if you wish. To learn it, https://www.facebook.com/groups/omado.s ... 597912865/
and to join it https://www.facebook.com/groups/omado.sosti.matiko/
Suggestions are also welcome; all suggestions, even in the form of unfriendly criticism, are put to practice if possible.
You cannot make a mistake in SostiMatiko, as long as you make yourself understood in it.
