一体
Meanings
what on earth; why in the world; who or where the heck
Placed before an interrogative word such as 何, 誰, どこ, なぜ, or どう to make a question emphatic. It often expresses surprise, confusion, suspicion, or irritation, but is not inherently vulgar.
What on earth happened?
Where in the world did he go?
one whole; single unit or group; single form or style
Noun use for things functioning as one body, unit, group, mass, form, style, or format. Common in patterns such as 一体となる, 一体にする, and 一体のデザイン.
The team fought as one until the end.
We brought the whole thing together in a unified design.
one statue or sculpture; one corpse; one remains sample
Only when written 一体 / １体
Numeral-counter use with 体, especially for Buddhist images, statues, figures, corpses, and samples of bones or remains. The Arabic-numeral spelling １体 is mainly useful in such counting contexts.
One Buddhist statue is enshrined in the main hall.
One body was found at the scene.
generally; on the whole; for the most part
Adverbial use, often as 一体に. It is somewhat written or formal compared with more everyday expressions such as 一般に or だいたい.
See also: 一体に
In general, winters in this region have a lot of rain.
strictly speaking; in the first place; originally
Dated adverbial use. In modern Japanese, そもそも, 本来, or 厳密に言えば is usually used instead, so this sense is most likely to appear in older or explanatory contexts.
In old writing, 一体 may be read with the meaning 'to begin with' or 'originally.'
