By the way how do you spell?
In the Russian language there are words used both as adverbs and as nouns. This is where the spelling confusion arises. For example, the word "by the way" how to spell?
This word is used most often as an introductory word meaning, that is, in addition to what was said. In this case, it is written together and is separated by commas: "By the way, I am familiar with it."
The adverb "by the way" is always written together. It means the timeliness of something (“Your comment came in very handy”) or is used in the meaning of “at the same time” (“By the way, do not forget about ...”).
With the noun “to become,” the preposition “to” is written separately: “This clothing was very suitable for his stature (stately figure).”
