This pattern is similar to ながら but adds a sense of contrast or concession. It means that the first part is true, but the second part is unexpected or opposite. For example, 高いながらも means 'although it is expensive' and implies that despite the price, something is still worthwhile. It is more formal than けど or でも, and is often used in written language or polite speech.

You can use it with verbs like 知りながらも ('although I know'), with nouns like 素人ながらも ('although I am a beginner'), and with adjectives like 古いながらも ('although it is old'). The pattern often appears in narratives, essays, or formal conversations. In casual speech, you would use けど instead.
