However, Nosuke doesn’t believe in UFOs, so he thought reading a book like this was stupid. “Baka” doesn’t hurt because they are used to talking to each other in such a playfully rude way.

俊：最近はユフォー学入門と言う本を読んでる。

乃介: こんな本を読むとか馬鹿なの？

Use baka to look down on or insult someone

Shizuka and Tarō are classmates. Tarō has a crush on Shizuka. One day, a basketball tournament was held at the school. Students gathered in the gymnasium to watch the game. Shizuka, the girl, is cheering for a player named Yamamoto. Unfortunately, Tarō heard it, got jealous, and muttered that Yamamoto was a “bakayaro.”

静佳: 山本先輩は本当にかっこいいです！

Shizuka: Yamamoto-senpai is so cool!

太郎: あいつは馬鹿野郎だ。

Tarō: That guy is a stupid jerk.

“Bakayarō” is a commonly used compound word that combines “baka” and “yarō” (野郎). “Yarō” is also a highly context-dependent word. It means “man” or “dude” when being used among male friends to mock each other. However, it turns to “jerk” or “dumbass” if you are meaning to offend someone.

Additionally, Japanese people sometimes put “大(おお)” before “馬鹿” to emphasize the degree of foolishness at hand — e.g. 大馬鹿, 大馬鹿野郎, and 大バカ者.

Baka’s other usages

Now that we’ve seen the essential usages of “baka,” let’s take it a step further. “Baka” can also be used as a prefix for adjectives and nouns to indicate excessiveness, which is similar to “very” or “super.”

Another frequently seen meaning of it is “useless” or “broken.”

Baka’s history and origin

At this point, I believe you have become a master in “baka” now ; ) In this section, I would like to introduce the two most significant theories about the origins of “baka.”

A Chinese idiom 指鹿為馬

The most widely accepted theory about “baka’s” origin is that this word was derived from a Classical Chinese idiom, 指鹿為馬. Before reading the history behind the idiom, please note that it contains the two Kanji that make up the word “baka”, “鹿” and “馬” — respectively meaning “deer” and “horse” in both Chinese and Japanese. Furthermore, the literal meaning of the idiom, 指鹿為馬, is “pointing at a deer and saying it’s a horse.” Am I kidding? No.

Once there was an emperor of China called Hu Hai, who was the son of Qin Shi Huang (259-210 BC). Hu Hai was too young to be a sovereign in power, which meant that the country was actually controlled by the prime minister, Zhao Gao. This evil vassal eventually had the idea of replacing Hu Hai on the throne. To carry out such a vast conspiracy, Zhao first needed to know he or the emperor had more respect from the officials in the court.

One day, Zhao presented a deer to the emperor and said it was a rare breed of horse. Hu Hai, the emperor, asked doubtfully, “Isn’t that a deer?” Zhao insisted it was a horse as he observed the officials’ reactions. Some officials were more outspoken and said it was a deer, while some, out of fear of Zhao, chimed in and said it was a horse. After that day, Zhao assassinated those who referred to it as a deer.

Now you can probably understand why this Chinese idiom, 指鹿為馬, refers to deliberate misrepresentation. As I mentioned above, this is the most widely accepted theory about the origin of the Japanese word “baka” (馬鹿), even if it doesn’t mean exactly the same thing as the idiom.

Baka is a loanword from Sanskrit

Another well-known theory argues that the word “baka” is a loanword from Sanskrit. Sanskrit is the sacred language of Hinduism and is also used to transcribe Buddhist classics.

A Sanskrit word, Moha (मोह), is considered by many linguists to be the origin of the word “baka.” It means bewilderment, loss of consciousness, delusion, or folly. This claim seems to make more sense in terms of meaning than the previous one.

Other Japanese swear words

At this point, we have nailed down “baka,” but now I’d like to introduce you to several otherJapanese curse words and pejoratives. I have to say that Japanese is not a rich language in terms of profanity, especially compared with English and Chinese. Still, there are some quality insults out there for us to dig into.
