Simply put, a fictitious concordance occurs when the fit between a subject and their verb (or, in some cases, a pronoun and its predecessor) is determined by meaning and not by form. I would have liked to think about the question. This is an excellent illustration of an interesting feature in the English language. But in fact, this example was stolen in a fairly excellent article recently published online by the people of Merriam-Webster. The subject: fictitious agreement. If the formal agreement is not concluded to us, we will have a fictitious agreement. If our teachers have never taught us such rules, how do we know they exist? “We don`t know who first recognized that the fictitious chord exists as a powerful force in English grammar,” says Merriam-Websters Dictionary of English Usage, “but it must be a fairly new discovery. The grammars of the 18th century never threw themselves on it, even if their examples of corrections showed that it was widely used. “To discuss the agreement with collective names (in American English and English English) see American English. Most English speakers are familiar with the basic rule of subject-verb agreement: a singular noun adopts a singular verb and a plural noun adopts its corresponding plural. Although the fictitious correspondence is more often used in British English than in American English, a certain amount is natural in each variety of English.
American style guides, for example, give advice on fictitious suitability for phrases like a certain number of, many, and a sum of. The AMA Manual of Style says: “The number is singular and a number of plurals”  (therefore, the number of mosquitoes is increasing, but a number of brands of mosquito repellent products are available) and “The same goes for the total number and a sum of (the total number of volunteers has increased, but a total of 28 volunteers applied [no *a]). It is the same concept that is covered by the Chicago style (16th edition) at “5.9 mass noun followed by a prepositional sentence”, but not all relevant nouns (including the “number”) are mass substanators.” Officially pluralistic nouns such as news, means and politics have long adopted singular verbs; Therefore, if a plural noun, considered as a single entity, adopts a singular verb, the fictitious concordance is at work and no one opposes it [the United States sends its ambassador]. If a singular noun is used as a collective noun and adopts a plural verblage or plural pronoun, we also have a fictitious agreement [the committee meets on Tuesday] [the group wishes to publish its views]. Indeterminate pronouns are strongly influenced by fictional concordance and tend to take on singular scars, but plural pronouns [each must show identification]” (Merriam-Webster`s Manual for Writers and Editors, rev. ed. Merriam-Webster, 1998) If you haven`t heard of a fictitious deal yet, it may be partly my fault. I have talked a lot about related topics, for example. B how to know which verb to use with “a herd of seagulls”. Is it “A herd of gulls is above the head” or “a herd of seagulls is above the head”? (Brief answer: both can be accurate, as we`ll see in a minute.) But the fictitious deal goes beyond these two scenarios.
