Q: What is the difference between “だいたい” and “たいてい”?
A: Both have the meaning of “approximately,” but their usage depends on the words that follow.
だいたい (JLPT N4)
When omitting fine details, focusing on the key points is the intended use. It is also used to indicate approximate ranges of quantities or time. The grammatical forms include “noun” and “adverb.” Similar words include “approximately” and “roughly.” When used with nouns, it is often accompanied by “の.”
[Examples]
その話はだいたいわかりました。
I roughly understood the story.
⇒ This implies that while some finer points remain unclear, the general idea has been understood.
東京から大阪まで新幹線でだいたい1万5千円ぐらいかかります。
It costs about 15,000 yen to take the Shinkansen from Tokyo to Osaka.
⇒ This indicates an approximate cost, leaving out exact details.
だいたいの人が会議に出席しました。
Most of the people attended the meeting.
⇒ This indicates that the number of attendees corresponds approximately to the overall total.
Additionally, “だいたい” can also mean “originally” or “in the first place.”
In this usage, it conveys a negative nuance and is employed to point out the cause of an undesirable result.
[Examples]
だいたいあなたが何もしないから、全部わたしがしないといけないんだけど。
It’s basically because you don’t do anything, so I have to do everything.
⇒ This emphasizes that the reason the speaker has to do everything lies with “you.”
たいてい (JLPT N5)
It refers to a large portion or almost all of a whole. Rather than indicating quantities or time ranges, it is used to express frequency, habits, or general tendencies with a high degree of regularity or certainty.
The grammatical classifications are “noun” and “adverb.” As a noun, it conveys meanings like “most of” or “almost all,” and as an adverb, it means “generally,” “normally,” or “usually.” When used with a noun, it is accompanied by “の.”
[Examples]
たいてい家の近くのスーパーで買い物します。
I usually do my shopping at a supermarket near my house.
⇒ This indicates that the speaker generally shops at a supermarket near their home.
たいていの人がダムの建設に反対しました。
Most people opposed the construction of the dam.
⇒ Many people were against the construction of the dam.

Let’s Compare
Let’s examine the differences using commonly heard phrases as examples:
[Examples]
日曜日はだいたい家にいます。
I am at home most Sundays.
日曜日はたいてい家にいます。
I am usually at home on Sundays.
Using “だいたい” implies that while there are Sundays when you are not at home, you are at home on most Sundays.
On the other hand, “たいてい” conveys that you are habitually at home (as a routine) or are at home on nearly all Sundays (high frequency).
