A simple question, why does the lower half of 安全 (safe), have the female character: 女 ？
Is it implying that safety pertains only to females being secure? Or is there no such implication?
I'd like to know why 女 was chosen
Splitting the character 安, we get 宀 + 女.
In oracle bone script, 宀 stands for house, and 女 means bride. The whole caracter means "bride in new house" (i.e. marriage).
In traditional Chinese culture, marrying a girl is a huge settlement in a man's life, so 安 means 安定 (settled), 安心 (relieved).
Reference is in full Chinese (so it's a bit hard for learners to read).
The comment by @dan is correct -「安」depicts a kneeling girl/woman in a building, indicating the meaning sitting peacefully > peace, quiet. It does not mean bride in new house.
Please don't use Vividict as a resource. It contains decidedly non-mainstream interpretations.
「安」was originally composed of「宀」(building),「女」(picture of a kneeling girl/woman), and an extra mark located around the area between the woman's heels and buttocks, emphasising that the woman is in a kneeling/sitting position.
Red line in the first form points to the small mark, which later became exaggerated.
The mark started being omitted in the Warring States period and completely disappeared after the Western Han.
Shapes that look like「安」before the Warring States without the mark may be considered to be a variant of「賓」instead.
