Translation guide
The English word 'thoroughbred' primarily refers to a specific breed of horse, but can also describe a person of exceptional quality or breeding. In Japanese, the horse breed is usually referred to by the loanword サラブレッド, while describing a person requires different expressions depending on whether you mean 'well-bred', 'elite', or 'purebred'.
Referring to the specific breed of horse known for racing.
The standard Japanese term for the Thoroughbred horse breed. It is a loanword from English and is widely understood.
彼はサラブレッドを育てている。
He breeds thoroughbreds.
サラブレッドのレースを見に行った。
I went to see a thoroughbred race.
Literally 'purebred species'. Can be used for thoroughbred horses in a more technical or general sense, but サラブレッド is more common for the specific breed.

Describing a person who comes from a distinguished family or has refined qualities, often implying good upbringing or natural talent.

He is on the elite track.
