Yes, indeed. The next point I was going to talk about was rhymes in artificial languages, like Esperanto. It is easier to make rhymes in Esperanto than in English or even Spanish or Latin. This over-simplicity, however, also makes it less exciting.
Yes, some of the early Esperanto poems and song lyrics came across as really stupid because they were just making easy rhymes out of participles and immensely common analytical suffixes like -ulo, a person who has the condition expressed by the root adjective. Since then Esperanto poets established the convention that it's not allowable to build a rhyme that only involves an inflection or another suffix--or even a whole series of them, which isn't hard to do in Esperanto. The last syllable of the root word also has to rhyme, no matter how far back it falls in the compound. Since the analytical nature of the language makes Esperanto's basic vocabulary very tiny, writing poems suddenly became hard work, but the results are more artistic. Its phonetic structure is rather like English, with a lot of tongue-twisting consonant clusters. It's hard to find two root words that rhyme.
Best langauge There may not be a 'best language' but I regard it as likely that over time, the world will progress towards a universal language and which language that is will be determinedby economic rather than practical factors. English is a great language with a massive vocabulary but with atrocious orthography. If we had the wit to resolve the problems which our bizarre orthography imposes, then English could be the language of the future but I doubt we have to wit.
