## What happens

Wittgenstein discusses the complexity of ordinary language, noting that while humans can construct languages to express any sense, the underlying logic of language is hidden by its colloquial form. He compares language to clothing that disguises thought, making it impossible to directly infer logical structure from surface grammar.

## Key lines

> Language disguises the thought; so that from the external form of the clothes one cannot infer the form of the thought they clothe, because the external form of the clothes is constructed with quite another object than to let the form of the body be recognized.

Ordinary language hides the true logical structure of thoughts, just as clothing is designed for purposes other than revealing the shape of the body.

_Illustrates the gap between grammatical form and logical form._
