Linda, Belle, and Bella (used as names) don't originate from the words meaning "pretty". They just coincide with them. Linda is a name of German origin meaning "flexible, soft, mild", Bella is just a short form of Isabella, and Belle is a short form of Isabelle. Bonita, on the hand, comes straight from the Spanish word and is not an actual name used in Spanish-speaking countries.
琳达,贝尔,和贝拉(作为名字使用)并不起源于意思是“漂亮”的词。它们只是巧合。琳达是一个德国起源的名字,意思是“灵活的,柔软的,温和的”,贝拉只是伊莎贝拉的简称,而贝尔是伊莎贝尔的简称。然而,博尼塔则直接来源于西班牙词语,不是西班牙语国家真正使用的名字。
