"There were straight rows of rally participants in the streets, the first of them carried a huge banner before the formation, " "He loved accuracy, so he wrote all the letters on clean white paper on a banner, " "In order to make a banner, they use liquid crystals, " the old film was shot when there was no computer technology yet - using the transparency method. " If you read these sentences and did not find any connection in them - it does not matter. The main thing is that you noticed that the word transparency is used in each of them. In which case is it used correctly? Difficult to answer again? And again, it’s not scary, because after reading the article you will immediately understand what is the matter and, of course, will understand what a banner is.
Where is the confusion?
The confusion about how to use words correctly and what they mean, sometimes arises due to such phenomena in the Russian language as homonymy and polysemy of words. Homonyms are words that are written and pronounced identically, but meanings have different meanings. Even in dictionaries, the interpretation of such words is given in different articles. Ambiguous words are divided within the framework of one dictionary entry, because, despite the different meanings, they still have something in common. The word "transparency" is just such a polysemous word and homonym at the same time.
What is a banner?
Let's start with the simplest and most familiar definition. Many people know that a banner is a large canvas that is used for the purpose of any propaganda or advertising to communicate certain information to a large number of people.
Physicists and lyrics … use the banner
In the second sentence, which we gave as an example of the use of the word (about letters), a banner is a device for writing smoothly on non-lined paper, it is a dense sheet with clear lines that fits into the paper on which you need to write something - the bands shine through and the writer does not stray from the line.
And what kind of banner, for the manufacture of which liquid crystals are needed? But physicists will not have such a question, because they themselves have repeatedly encountered transparency when they had to determine the characteristics of light. In physics, a device is called a transparency in the form of a thin plate, due to which the properties of a light beam can be determined.
