विज्ञानी (vigyaanii)

noun Means 'scientist' -- a person who works in science. Closely related to विज्ञान (vigyaan, 'science'), from which it is derived; also compare वैज्ञानिक (vaigyaanik), the more common word for both 'scientist' and 'scientific'.
Sense 1 : scientist
noun, masculine
Synonyms: वैज्ञानिक (vaigyaanik)
Frequency: medium
Cultural Note: Both विज्ञानी (vigyaanii) and वैज्ञानिक (vaigyaanik) come from विज्ञान (vigyaan, 'science'), but if you turn on Hindi news or read a school textbook, वैज्ञानिक (vaigyaanik) is what you will hear used for 'scientist' nearly every time; विज्ञानी (vigyaanii) shows up more in written or slightly elevated registers.
Common Mistakes: 1) Learners often default to वैज्ञानिक (vaigyaanik) for 'scientist' since it is far more common in everyday speech and news; विज्ञानी (vigyaanii) is understood but sounds slightly more formal or literary in comparison. 2) Do not confuse with वैज्ञानिक (vaigyaanik) used as an adjective meaning 'scientific' -- विज्ञानी (vigyaanii) is only ever the person, not the adjective.
