An observation after rereading §58-61 of Wittgenstein’s Investigations, in the light of my recent readings of Kant/Frege/Russell/Quine:

Wittgenstein isn’t completely denying the compositionality of grammar, which is what the linguist would like to maintain, but only objective compositionality, or the idea that (for example) the word or concept of a broom is equivalent to the concepts of the broomstick and brush fixed together.
