genius takes the preposition 'for' + gerund, not 'to' + infinitive.

Synonym discussion

Sense: noun/1

All four words describe exceptional ability, but they differ in degree and focus. Talent suggests a natural ability that can be developed through practice — a talented person works hard and improves. Genius implies something rarer and more extraordinary, a level of ability that seems almost superhuman. Brilliance focuses on intellectual sharpness and the quality of being exceptionally bright or quick-minded. A prodigy is specifically a young person who shows genius-level ability early in life (e.g. a child prodigy on the violin), whereas genius can describe someone of any age. Intellect is more about raw mental power and reasoning ability than creative originality. For example: 'Mozart was a musical genius' (not just talented) describes a level far beyond 'She has a talent for drawing.' A child who plays chess like a grandmaster at age seven is a prodigy; an academic with vast knowledge has great intellect.

Etymology

LatinFrenchEnglish

Genius comes from Latin 'genius', which in ancient Rome meant the guardian spirit or innate character assigned to each person at birth. This Latin word comes from 'gignere', meaning 'to produce' or 'to beget' — the same root that gave us 'gene' and 'generate'. The modern meaning of 'exceptional intellectual or creative power' developed in the 18th century during the Enlightenment, when thinkers began to describe extraordinary artists and scientists as having a 'genius' — a special innate gift that set them apart.
