What does Desu mean in Japanese?
The word desu [です] is nothing more than a polite version of "da" [だ]. Its common use in the Japanese language generates various discussions regarding its meaning, so let's examine it in depth in this article.
Its use is quite simple, the desu [です] goes at the end of sentences to indicate the idea of "to be" or "is". The da (だ) can also be used to indicate the past of an action or the imperative form of a verb.
These words can come after any word to emphasize, equate, assert, and declare something. It is a simple formality to end the sentence correctly, with no actual effect on the sentence.
It is not mandatory to use these in Japanese conversations and sentences, but their use is fundamental to enrich the conversation and make the sentence more polite. Another alternative to desu or da is dearimasu [であります].
Is Desu really the verb to be in Japanese?
Some claim that desu is the verb to be, but others claim it is not a verb. In reality, desu [です] cannot be a verb, since it is generally used together with a verb.
Explaining in a more technical way, the desu [です] is actually a Japanese copula (link), used to grammatically relate a subject to a predicate. Even though it is translated as is or to be, desu cannot be called a verb.
The form da [だ] is an informal way of using desu [です] that tends to be as natural and common in most informal conversations as a simple particle. Both da and desu are also referred to as verbal auxiliaries.

Simplifying the meaning of Desu
The da and desu are one of the first things we learn when studying Japanese. Some people get quite confused with the meaning and usage of this particle which should be very simple.
To make it easier we can simply compare the desu [です] with a sign of = (equal). Where its main function is to say that A is equal to B.
In Japanese there are 3 ways to end a sentence or sentence:
- With the copulas だ/です;
- Verbs;
- Adjectives ending in い;
Sometimes it is used with a complementary or emphasis particle. Some use [です] at unnecessary times such as with [い] adjectives, just to make the sentence more formal. Don't start using [です] randomly just because you think it sounds nice.
