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.
He breeds thoroughbreds.
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.
This horse is a thoroughbred.
Describing a person who comes from a distinguished family or has refined qualities, often implying good upbringing or natural talent.
Means 'well-brought-up' or 'from a good family'. It focuses on upbringing and manners rather than lineage alone.
She is well-bred, so she is always polite.
Loanword meaning 'elite'. Used for people who are top in their field, often through education or career, not necessarily family background.
Means 'born and bred' or 'true-born'. Used to emphasize that someone is a genuine example of a type, e.g., 生粋の江戸っ子 (a true Tokyoite). Can imply pure lineage or deep-rooted identity.
He is a thoroughbred New Yorker.
Referring to any animal of pure breed, not specifically a horse.
While 'thoroughbred' can metaphorically describe a person in English, the Japanese サラブレッド is almost exclusively used for horses. Using it for a person would sound odd or like a joke.
He is a thoroughbred. (unnatural)
彼はエリートコースを歩んでいる。
He is on the elite track.
I'm looking for a thoroughbred cat.
