This noun describes a distinction or differentiation—a marked difference that separates one thing from another. Paul uses it to emphasize the absence of distinction between Jew and Greek in matters of sin and salvation. All have sinned, there is 'no distinction'—both groups stand equally guilty and equally in need of grace. The same Lord is Lord of all, showing 'no distinction' between groups. In musical contexts, instruments must make 'distinction' between notes or the melody is unintelligible. The term highlights boundaries, differences, and the presence or absence of discriminating factors.
