1.
accent, stress, intonation
The pitch or stress pattern in spoken language. In Japanese linguistics, this refers specifically to pitch accent.
2.
accent, highlight, focal point
A feature that adds contrast, emphasis, or visual interest to something, such as in fashion, interior design, or cooking.
Usage
Sense 1 is used in linguistics and language learning. Japanese has a pitch accent system (高低アクセント), not a stress accent system like English. Sense 2 is common in fashion, design, and cooking contexts where something adds contrast or a focal point.
Common collocations
Watch out
For a regional or foreign accent in the English sense, Japanese usually says 訛り: 訛りが強い (to have a strong accent). アクセント means the pitch pattern of a word.
