I take it as an injection 3 >2, as it were: I think that elements in 3 have also to be in 2.

I don't think that a tree is considered a mass at all (usually, anyhow).  It is green just because that is the way we use that word -- analysis might suggest something about what they way is but would not change the humanly primitive use here.

<> Agreed, we can live with an implied pisu'o on {lei bolci}, but you can't

Well, it is one way to get consistency into the mass system, the next step will be to make the system intensional, which is generally something to be avoided as long as possible.

Too late for an English lesson here, though what examples you want is unclear, so you are apparently reporting accurately.  What I think you may be trying to say is that you can't find a case where xorxes agreed to something that I said that clearly made the size of the set different from the size of the mass.  You are right in that; I misunderstood xorxes' definition of {mei}.

<>> I think tatpi is a particularly bad example.>

It is a good example of a particular kind of problem,one where it is difficult to say what "sum" means in very explicit terms.

Right, which is why {tatpi} is a good example -- though I am not sure that tired legs is enough for a man to be tired.
{xo le nanmu cu tatpi} -- {kau} is only for subordinate clauses.

Certainly not {ijo}; for one man (say) might be tired but the whole group not.  It might even be the case that the group was tired though no one member was, I think (if not {tatpi} then surely something else will work here).
