What part of the speech is the word "pier" in the sense of "do we know what they say"? Where did it come from?
MOL is an introductory word, a conversational style. It has two meanings: 1) Transmit someone else's speech, someone else's opinion; 2) Transmission of own speech, expressed by the speaker himself earlier.
Thus, the word has a great deal of work: in fact, it serves as a designation of direct speech, and even in a conversational style.
A pier is a particle. When used, shows that the speaker passes someone else's words or talks about the past. And he says to me, they say, it's necessary to marry; - conveys other people's words.
Thus, MOL refers to a particle, namely to modal particle, conveying the words of a stranger, referring to words spoken not by the narrator, but by another person. MOL-abbreviated from say-say, talk. In addition, in colloquial speech, a particle can also be used to DESCEND, -De: He can not come.
quot; molquot; from quot; say "; Another similar particle quot; dequot; (from quot; say;); it is always written with a hyphen. In the Old Russian language, it was mandatory when transmitting someone else's speech.
He said that he was not there and did not know anything;
Do not confuse morphology with syntax, that is part of speech with an opening word.
In the quot; Russian Dictionary; quot; S.I. Ozhegova, for example, the word MOL interpreted as a masculine noun
and as an introductory word:
Obviously, in the above sentence, the introductory word is used in its meaning. MOL, and the introductory words should always be allocated with commas, that is, correctly write the sentence like this: "We know, MOL, suchquot ;.
The etymology of the word was given by all previous authors of the answers, and the Ozhegov dictionary also indicates the formation of this word. But I will try to answer the second part of the question.
I can not agree that this word is quot; superfluous; If it is omitted, the meaning of the whole sentence will change:
it will express the thought of the speaking person himself.
Parenthesis MOL indicates precisely that the expressed thought belongs to a non-talking person, and this person conveys someone else's idea.
Parenthesis MOL has synonyms DREAM and a particle Dewith which it can be replaced.
