Which features make a language easier to learn for children learning a constructed language as L1? Are children learning a language with these features able to learn the language faster than a natural, irregular language without some of these features?

  • Downvoter care to explain?

Difficult question. I think regularity would speed up learning, as children during language learning overgeneralise (see experiments with English past tense endings). Thus instead of learning the correct exceptions at a later stage the corresponding feature would have been learned earlier.

There is a programme for teaching Esperanto as a first foreign language, as it can be used to increase second language awareness and is supposed to make learning a natural foreign language easier. You don't have to worry about exceptions, for one thing, so you can teach the concept without having to hedge your explanations by listing all the cases where it's different.

My personal view on 'difficulty' of different languages is that all languages are about equally difficult. Some languages are easier/simpler regarding some features (English inflectional morphology), but make up for that in others (vast number of near-synonyms with different distributional characteristics in English). Toki Pona is a very simple language (120 words, virtually no syntactic complexity), so you can learn it almost in a day, but it is very hard to express complicated narratives, and an equivalent text in a more complex language would be far more concise.

Learning Esperanto is reasonably easy, but then you look at how people actually use it in everyday interactions, and you find that it is more difficult than you imagined: there are a lot of the smaller particles that make it tricky to understand for a beginner. But the 'early' sentences composed when the language was still fairly new are a lot simpler. However, they were not suitable for encoding all the pragmatic and other information people need for an everyday language.

So, there are undoubtedly features that make it easier for children to learn a language as L1, but the question is "what for?" It's a bit like learning Lisp programming: understanding the syntax takes literally ten minutes, but that does not mean you can write useful programs in it after that. Languages are more than the sum of syntax and vocabulary, and if there was a language that was easier to learn and use than other languages, and had equal expressive power, then we would all be speaking it already.

  • I've accepted this as the correct answer. Could you give an extra explanation of paragraph 4?

    You mean the Esperanto particles? I found that in the Eo learning literature the sentences used are always very straight forward and easy to understand. But in 'real' texts (eg on twitter, or even Eo stackexchange) a lot of the smaller particles are used whose meaning is very dependent on the context. I personally find that a lot harder to understand. Commented Apr 26, 2018 at 11:45

    How about some examples of these ‘smaller particles’? Commented Oct 4, 2018 at 7:01

Children learning an L1 have most of the same challenges as people in general learning an L2. Children learning a conlang, will have all of the problems of children learning a non-community language from a parent-- mostly problems of exposure. Kids need to hear the language for something like 20+ hours a week, less than that and they start to learn a pidgin form that is simplified. See the literature on language death for more about that process.

A rich vocabulary is hard. Teachers of languages say that the shear amount of vocabulary you need to learn is a major barrier to learning a language. This is why auxlangs try to pick words that are highly similar to what someone already knows. toki pona takes the idea of vocabulary reduction to about as far as it can go, but in my experience with it, it still feels like you need to memorize about 3000 set phrases whose meaning can't easily be guessed from the parts.

Morphology is hard. Analytic languages are going to be less difficult. In communities where a polysynthetic language is dying, the kids start using it as if it were analytic, i.e. with sentences with more words instead of one spectacularly complex verb.

Lexicalized grammar is hard. This is when you make up words instead of applying a grammatical rule. For example, in German, you have to just memorize most plurals as a second word. It is easy to accidentally create lexicalizations if you mother tongue has them. For example, in some language antonyms are phrasal or morphological modifications of a base word, in English and other languages, antonyms often are a separate word. My son right now is at the point where he over-regularized past tense English verbs, an indication that lexical past tense forms, (see, saw, eat, ate, etc) are hard, even for kids.

  • Actually, linguistic features tend to cycle between being isolating, agglutinating, and inflecting. Isolating componants can evolve into agglutinating affixes, and sound change can merge chains of agglutinating suffixes into a singular ending. People then may start to drop the endings if they get tired of all the complicated declinations. Though this doesn't always happen. Yes, this happened with Latin, but it hasn't happened with the Slavic languages.

  • In general, each of the three has their own advantages and disadvantages. Isolating languages tend to be simple and regular, but they aren't great if you want to pack in a lot of information (note that isolating languages tend to omit things like number and tense). Agglutinating languages are simple, regular, and detailed, but they take a while to say things. Inflecting languages can pack in a lot of information without being long-winded (a single vowel on the end of a Spanish verb, for instance, can indicate person, number, tense, aspect, and mood). But they're complicated.

  • Thus, none of them are perfect, they all have their own advantages and disadvantages. And also, analytic languages aren't necessarily easier. Research on L1 aquistition clearly shows that people pick up case markings faster than word order. Which makes sense if you think about it. With analytical languages, a noun phrase's role in a sentence is indirectly implied base on the order everything is put in. With languages that mark case, the role a noun phrase plays is directly stated. And people who are used to this find analytical languages to be unfathomable.

  • Though part of that is because of 'conditioning'. Often times languages with case marking will have one be marked by a null morpheme. This means that if they hear a noun with no case marking, their instinct is to assume that its in the case that's unmarked in their native language. Same thing as how English speakers tend to automatically assume that every noun is singular in languages that don't mark plurals.

  • You say “Analytic languages are going to be more difficult,” which surprises me, but then you contradict it. Maybe you want to edit that? Commented Oct 4, 2018 at 7:02

Human beings first develop with a sense of Self and not being able to distinguish between "Self" and "The World". Things are seen as "Images" and "Objects", only later are abstract ideas understood. Human languages started off as SOV (Subject-Object-Verb) but later changed to different word orders.

With that being said, these features would make it easier to learn languages.

  • Common Phonemes (/m/, /k/, /i/, /a/, /j/, /p/, /u/, /w/)

  • No Consonant Clusters ( mk, mp, kp, pk)

  • Noun based (let verbs and adjectives derived from nouns)

  • Let any complex words have it's root from the simple (For Example: "Hospital" could be "Health-House" or "Healing Place").

Just like human beings start of learning simple things, then complex, let all "big" words be form from compounds of smaller ones.

  • Remember language Universals. Frontal vowels (/i/) are usually used in words that represent smallness, sharpness, brightness, closeness, and hapiness. The sound /i/ uses the same muscles as when a human being smiles.

Back vowels (/u/) are usually used in words that represent bigness, depth, roundness, smoothness, darkness, dirtiness, far-distance, and gloominess.

Toki Pona has some of the features of what an easy language would look like. Good luck to inventing an easy/minimalist language. Cheers!

    Hello and welcome to the Conlang site. Please consider editing this to add some references to sources which back up the claims you have made here. I'm not sure about everything you've said here... while consonant clusters may be tricky for children learning language, I doubt something like [mk] makes a difference for adults, and I'm very sceptical that /i/ is used "in words that represent smallness, sharpness, brightness, closeness, and hapiness".

    What about misery? Not really related to happiness... Those claims are usually bogus. Also not sure about SOV as the 'initial' sentence structure. I never heard that before in 25 years of being a linguist. Commented Jul 30, 2018 at 8:08
  • The obvious response to the claim about frontal vowels like /i/ representing small things and back vowels like /a/ representing big things is to point out the words "small" and "big". Commented Nov 1, 2018 at 20:58
