Object/Frege: the object is the meaning of a declarative sentence. It is at the same time the truth value and value curve of a function.

Value propression.
(A school-adequate definition of an object is impossible, because it cannot be disassembled - due to its simplicity.)
An object is anything that is not a function, i.e. whose expression does not carry an empty space with it.
Truth value: A truth value cannot be a part of a thought any more than the sun, because it is not a sense, but an object. (truth value/Frege: a truth value is an object)
Object/Frege: locations, times, time periods are, logically considered, objects. Consequently, the the linguistic designation of a place or date is to be interpreted as a proper name.
Def Object: Something that can never be the whole meaning of a predicate, but the meaning of a subject.

"The function f(a)" is not a function (but an object).
"The concept F" is not a concept (but an object).
I am not saying it is wrong to say about an object what is being said here about a concept, but it is impossible, meaningless, neither false nor true.
Existence proposition/existence statement/Frege: e.g. "Julius Caesar exists" is neither true nor false, but meaningless. But:
"There is a man named Julius Caesar" has a sense. (A concept is needed.)

Object/Frege: an object should be the result to which the predicates refer according to the judgement.

Frege II 57
Object/Frege: e.g. places, times, time periods - hence their linguistic designations are names.
II 74
Concept/object/sentence/Frege: one and the same sentence can be interpreted
a) as a statement about a concept,
b) about an object.
The statements are then different. E.g. the sentence "There is at least one root of 4" cannot be changed into "There is at least one concept for the root of 4." ->
concept.

Object/concept/property/Frege: e.g. direction: is an object! - "Same direction as": is a predicate (concept).

Body/Frege: bodies are not in need of completion. (>(s) Objects are saturated).
