Russian is one of the most difficult languages, so it is not surprising that such a phrase as "in execution" causes difficulties in its correct spelling, because this preposition can also be written with the letter "i" at the end. In this article, we will try to explain in simple terms in which cases it is necessary to put the letter "e", and in which - "and".
When spelled with "and"
First of all, it is worth defining the original form of the word - it is a neuter noun "execution". As you can see, his ending is "-s", respectively, in the form of the prepositional case, it will be replaced by "-s". However, if we consider a neuter noun of the second declension, then in the prepositional case the ending will be "-e".
To better understand everything, let's apply the prepositional case to the word "performance". In view of the factthat this is a neuter noun, then the question will be "What?". For clarity, in the formulation of the question, we use the verb "hear". It will turn out: "To hear in what? In performance".
Now we know that in the prepositional form the noun "execution" is written with the letter "and" at the end.
When spelled with an "e"
Now let's figure out how to spell "in execution" correctly in Russian. First, you need to learn to distinguish the prepositional case of a noun from a derived preposition. Indeed, in the first case, as discussed earlier, the letter "and" is written. Secondly, it is this knowledge that will help with writing "in fulfillment." But let's get to the bottom of the problem.
The phrase "in execution" is more common in formal business style. After it, you can ask the question "What?". For example: "In pursuance of the decision." Also write the letter "e" at the end if the word can be replaced with "for the sake of performance".
Conclusion
As a result, we were able to figure out how to write correctly: "in execution" or "in execution". Finally, I would like to draw attention to one trick. If this phrase begins with "in", then in the vast majority of cases you need to write "e" at the end, if with "in", then use "and". This is, so to speak, a lazy rule. It doesn't give 100% certainty.correct spelling, but can also help you out in a difficult situation.
