		For in the printed proposition, for example, the sign of a proposition does not appear essentially different from a word.	For in a printed proposition, for example, no essential difference is apparent between a propositional sign and a word.
		(Thus it was possible for Frege to call the proposition a compounded name.)	(That is what made it possible for Frege to call a proposition a composite name.)
3.1431	The essential nature of the propositional sign becomes very clear when we imagine it made up of spatial objects (such as tables, chairs, books) instead of written signs.	The essential nature of the propositional sign becomes very clear when we imagine it made up of spatial objects (such as tables, chairs, books) instead of written signs.	The essence of a propositional sign is very clearly seen if we imagine one composed of spatial objects (such as tables, chairs, and books) instead of written signs.
		The mutual spatial position of these things then expresses the sense of the proposition.	Then the spatial arrangement of these things will express the sense of the proposition.
3.1432	We must not say, “The complex sign ‘aRb’ says that a stands in relation R to b”, but: That ‘a’ stands in a certain relation to ‘b’ says that aRb.	We must not say, “The complex sign ‘aRb’ says ‘a stands in relation R to b’”; but we must say, “That ‘a’ stands in a certain relation to ‘b’ says that aRb”.	Instead of, ‘The complex sign “aRb” says that a stands to b in the relation R’, we ought to put, ‘That “a” stands to “b” in a certain relation says that aRb.’
3.144	States of affairs can be described, not named.	States of affairs can be described but not named.	Situations can be described but not given names.
		(Names resemble points, propositions resemble arrows; they have sense.)	(Names are like points; propositions like arrows—they have sense.)
3.2	In the proposition the thought can be so expressed that to the objects of the thought correspond elements of the propositional sign.	In propositions thoughts can be so expressed that to the objects of the thoughts correspond the elements of the propositional sign.	In a proposition a thought can be expressed in such a way that elements of the propositional sign correspond to the objects of the thought.
3.201	These elements I call “simple signs” and the proposition “completely analysed”.	These elements I call “simple signs” and the proposition “completely analysed”.	I call such elements ‘simple signs’, and such a proposition ‘completely analysed’.
3.202	The simple signs employed in propositions are called names.	The simple signs employed in propositions are called names.	The simple signs employed in propositions are called names.
3.203	The name means the object. The object is its meaning. (“A” is the same sign as “A”.)	The name means the object. The object is its meaning. (“A” is the same sign as “A”.)	A name means an object. The object is its meaning. (‘A’ is the same sign as ‘A’.)
3.21	To the configuration of the simple signs in the propositional sign corresponds the configuration of the objects in the state of affairs.	To the configuration of the simple signs in the propositional sign corresponds the configuration of the objects in the state of affairs.	The configuration of objects in a situation corresponds to the configuration of simple signs in the propositional sign.
