* ಕೃತಕ (Krutka): This means "artificial" or "man-made," and is a direct opposite in the sense of something being unnatural.
* ಅಸಹಜ (Asahaja): This means "unnatural" or "abnormal" and refers to something that deviates from what is considered normal or expected.
* ಪ್ರಯೋಗಿಕ (Prayogika): This means "experimental" or "artificial" and implies something created or influenced by human intervention.
The best opposite will depend on the specific context and the nuance you want to convey.
For example, if you are talking about a natural phenomenon versus something created by humans, then ಕೃತಕ (Krutka) might be the best option. If you are talking about something that deviates from the expected norm, then ಅಸಹಜ (Asahaja) would be more suitable.
