Translation guide
The English word 'upright' covers physical verticality, moral integrity, and a specific piano type. This guide breaks down these distinct meanings and provides natural Japanese equivalents for each.
Describing a posture, object, or position that is straight up and down, not leaning or horizontal.
Refers to standing perfectly straight, often used for people or objects like poles. Common in compound verbs like 直立する (to stand upright).
Describing a person of good character, who is honest, fair, and follows strong moral principles.
Referring to the musical instrument with vertical strings, as opposed to a grand piano.
