samurai

This term evokes a strong association with the bushido code, emphasizing honor, discipline, and an unwavering commitment to one's lord. It carries a connotation of stoicism and lethal precision, often used to describe someone who is an expert in their craft or possesses extreme mental fortitude. Grammatically, the word is an invariant noun. In English usage, the singular and plural forms are identical, meaning "one samurai" and "ten samurai" are both correct, although "samurais" is occasionally seen in casual speech.
