In all the languages I know, at least one of the following aspects is complex/difficult:
- Alphabet: Complex meaning a large alphabet like in Chinese.
- Pronunciation: Complex meaning that, for example, small differences in pronunciation can lead to large differences in meaning as in Chinese, or that it is hard/impossible to infer a word's pronunciation from its spelling and vice versa as in English.
- Grammar : Complex meaning, for example, redundant information like conjugation plus personal pronouns as in German, or a complex mapping between grammatical concepts (case, number, time, ...) and change in word forms.
However, many languages seem to be "simple" in at least one of these aspects: Romanian, for example, has a complex grammar but simple pronunciation. Chinese languages, on the other hand, are said to have simple grammar (due to what I think are called invariant lexemes) but complex pronunciation (due to the usage of tone). Hence it seems plausible that there are languages which are simple in all of these (and other) aspects.
Are there any "simple" evolved languages? And if not, why?
