The Russian language is beautiful and terrible at the same time. The latter circumstance is especially felt when the great and powerful are painfully studied. How do foreigners master all this? Unknown Let's talk today about the difficult case, which is contained in the phrase "be absent from classes for a week." Nothing is in doubt here, except for the end of the word "current". But even this problem will seem easy if you find an approach to it.
The whole problem is in tune
Speaking in scientific language, this is called homonymy. There are several types of homonyms. We deal with homophones, because all the same by one letter, and the concepts differ, depending on what is meant. If we are talking about a time period, a period, then there is no mistake in the sentence “to be absent from classes for a week”. Another thing is if it is said that it has a course, even if it is about time. It is important to understand what exactly a person wants to say. But this is not the only criterion. First, we turn to parts of speech.
Derived or non-derivative preposition with a noun
We apologize to the reader for having to understand such subtleties, but cannot do without it when it comes to genuine knowledge. The world is so arranged: you need to sweat in order to achieve a result.
What is the difference between a derivative and a non-derivative preposition? In origin. The former were once other parts of speech — nouns, adverbs, and participles. Non-derivatives cannot boast such a rich biography. We think there will be no great harm in citing at least one example of both. A kinship with nouns has:
Prepositions related to adverbs are as follows:
Prepositions leading their lineage from the participles:
To illustrate non-derivative prepositions, you do not even need a list, we bring them to the line: c, s, k, o, y.
In this broad series, we are interested in how easy it is to understand, only the excuse is , since it is he who is involved in the proposal "to be absent from classes for a week." By the way, if someone else does not understand, then the example is written correctly.
Distinction problem
Naturally, you may not know the above subtleties, but not make mistakes when you need to show off your abilities. There are also rumors that there is some kind of innate literacy when a person, without remembering the rules, writes without errors. Well, maybe she is. But it’s better to know exactly why a person thinks so and not otherwise, and on what basis in the sentence “be absent from classes for a week” you should write exactly “e” and not “and”. So, let's start with the cases. When it comes to the preposition, the ex-noun in it stands in the accusative case. If we are talking about a noun with a non-derivative preposition, then the case is already different - prepositional. Hence the difference between endings. If the derivative preposition is “e”, if the noun with the preposition is “and”.
What to do if you are reluctant to torment yourself with cases?
If a word is mentally inserted into the space between the preposition and the alleged noun, then you can safely write the words “and” rather than “e” at the end. For example: "In the upper reaches of the river, my father and I found crayfish." Of course, the dependent word that stands in the genitive case can save the situation in this situation. As you can see, you can’t completely get rid of cases. True, if we think about the terms in general and the weeks, months in particular, it is unlikely that the dependent word in the genitive case will actually save the situation. So, you need to think first of all over whether there is a gap between the preposition and the noun. If not, then the design only pretends to be disguised as a noun and an excuse. It is clear. Now the reader himself is able to answer the question of how to correctly - "be absent from classes for a week" or "a student was not in classes for a week." We will only say that it is correct not to miss classes, but otherwise all keys are provided, you just need to think a little.
What do time and river have in common?
The verb "flow" unites them. Therefore, theoretically and practically, a situation may arise when it comes to time, but you still have to use a noun with a preposition, and not a non-derivative pretext. For example: “Over time, states and even entire civilizations disappear.” What are we talking about? That nothing lasts forever. And be that as it may, there is no mistake. You can insert an adjective into the space between the preposition and the noun, for example, “inexorable” in the appropriate form, and immediately doubts will disappear about how to write the phrase “over time”.
Disease and recovery time
There is such a famous phrase "the course of the disease." It can also be practiced to dispel the latest doubts about the subject of our scientific conversation. For example, like this: "During the course of the illness, no special changes were observed." And it’s possible in another way: “Petrov, please do not go to work during the illness so as not to infect the team and not break our deadlines.” The difference is only one letter, and the meaning is radically different. In the first case, we are talking about an ailment that is static, and in the second case, it is said about how long Petrov should not go to work.
Nevertheless, the most effective method of error protection in this sense is the study of the space between the preposition and the noun, whether it exists or not. True, a clear-thinking person may well say what he means. It is one thing - the course of a process, even if it is temporary, and another - during what period an event occurs. For the transparency of the foregoing, we will use the services of a pun: “Certainty during the illness will appear within a week.” Everything seems to be clear. Therefore, there should not be a problem with the proposal “to be absent from classes for a week” (we hope that we have explained the rule as a rule).
