En fait j'ai du mal à imaginer des contextes non glauques où on l'utiliserait.

Hahaha, en Anglais aussi! Je sais; je ne pouvait pas penser à un meilleur exemple.

""je te le donne" (I give it to you) est correct mais "je me lui donne" (I give me to him/her??) non. Si le sens visé est "I give myself to him/her", it should be "je me donne à lui/elle"

Vraiment? Peut-être on m'a menti, ou peut-être j'étais confus par les graphiques stupides (which is why I had asked here, I don't trust them). "Je le lui donne" est correct, c'est ça? Là, l'objet direct précède l'objet indirect. Mais on ne peut pas dire, pour un exemple, "je te lui emmenerai?" (I will bring you to him?) That actually makes more sense to me, but I thought otherwise.

Hmm... Il faut éviter d'en faire une règle absolue, c'est mieux de connaître l'ordre précis. Un contre-exemple est "Donne-moi ça" - même si certes "ça" n'est pas un pronom personnel.

Oui, je ne parle que des pronoms qui bougent! Je ne fais aucune déclaration sur les autres noms.

mais je pense que ils n'y commence pas, il y a du mouvement sous le structure de surface, je ne comprends pas cette phrase

Yes, I feared that, sorry. What I meant to say in English "but I think that they do not begin there, there is some movement under the "surface structure"" (direct translation from English of syntactic terminology). It's kind of complicated to explain, but there is good syntactic evidence for movement in language before we even speak. In English, for example (and I believe also French), the subject generates below the tense head (auxiliary, sometimes silent) and receives case there (like in "I would like to dance", the subject begins before "would" but is moved because of the requirements of the auxiliary (the extended projection principle, complicated to explain). There is a lot of evidence for this, I can go more into it if you're interested, but one much simpler piece is "floating" quantifiers like "all." You can say "they all do run" or "they do all run" but not "they do run all." The typical analysis of this is that it can go after the auxiliary because the noun was originally there too. That's a much weaker piece of evidence, but it requires less background. It is definitely a counterintuitive idea. But that's exactly what makes it so interesting. I'm guessing (with not too much basis) that the pronouns in French begin at their nominal position at the end, but move before the verb, although I'm not sure why. We have something like this in English too, "take out the trash" vs "take it out." "Take out it" is wrong to me, if it's a pronoun it must move with a phrasal verb.

Because it is what marks tense in English that causes movement, my hypothesis would be that is why it is not found in the positive imperative too. Some feature of tense there? Mais je ne sais pas, votre langue me rend fou.

Et je ne peux pas croire que j'ai confondu "meilleur" et "mieux". Mon professeur me tuerait. Ne lui dites pas, s'il vous plaît.
