In terms of logical view, our language activity already prepared for logical and mathematical sensibility we can share, on the contrary, logics sense could mimic language's our inherently known syntax and grammer idea.

Then, this time the most basic several ideas could be addressed for the first time.
First, our daily explannation to one condition at our utterance of conversation could be exampled. 

Eventually, our conversation's method we unconsciously use at daily life must rely on what we want to send to the conversation partner hte most.

Then, for making the one being known, we try to focus on our mind's own interest and subjective will, at both explannation at responding and questioning.

Ultimately,. limiting the talked subject as restricting the sent subject and modifying meant then necessarily  omitting unnecessary elements with decoration and ornamentation for making the talked one so understood.

Just for summarizing, understanding strucutre of language act with taking intention and consciousness and with its result, we take sending its content to sent one.

One more very vital function of our conversation means proposition's setting, and toward it, which we opt affirmation or nagation.

Then, its the most basic idea is almost the same and sharable to mathematics.
Let's have summary, here.

〇Our speaking sentences mean the realization of what we want to tell.

〇For articulating them, we usually use proposition as setting communicative proposition, and after we've done it, with its set proposition, we usually apply mentioning with both affirmation and negation or these developed contents.

Around these processes, we don't have any diffrence or gap between ordinary reporting sentences and questioning sentences. All sentences have no fundamentally complete same structure and main elements.

In other words, all sentences have main proposition, then in other words, what has no proposition is never sentence. This is the most integrally cardinal basic premise.

Then, this time at this last mentioning, two these examples could be provided.

①All of us need holiday or vacation. (Ordinary sentences)

② Are your holidays taken at ordinary holidays of callender with Sundays or so?（Questionable sentences）

Memorandum; When we confess the emotion or mind's fact to unidentified matter e.g. "I have so unidentified matter or thing." means to have a question, then it tends to confess that " I don't know.", then these all are intended to negate so essentially.
