disposition; nature; temperament
Refers to a person's inherent character or way of thinking, often with a nuance of kindness or good-heartedness. Somewhat literary or old-fashioned; in modern speech 気立て (きだて) is more common.
Everyone acknowledges her good-natured disposition.
Compound of 心 (こころ, 'heart, mind') and 立て (たて, nominalized form of 立てる 'to set up, establish'). The exact historical derivation is uncertain, but the word conventionally refers to one's established character or disposition.
