innate nature; natural disposition
Refers to a person's inherent character or natural qualities, often with a nuance of something bestowed by heaven. Somewhat literary and not an everyday word; 天性 (てんせい) is more common in modern speech.
彼の天資は芸術に向いている。
His innate nature is suited to the arts.
highly gifted; of exceptional natural talent
From 天 (heaven) + 資 (resources, nature). The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning of innate qualities.
