嫁is a Logical Aggregate and Phonetic Compound at the same time, formed from two semantic indicators of 女(literally means a female) and家(literally means home; a house; family) and 家 (not jià but jiā due to the years of evolution of Chinese phonetics ) is also defined as its phonetic component.
本义original meaning: 女子出嫁 (of a woman) marry
Lily explains 嫁like this:
As we have learned in the previous lesson of 安, in feudal age, a Chinese woman was not for her parents and herself but for her future husband and his family. From the perspective of a Confucian family, marriage brings together families of different surnames and so continues the family line of the paternal clan. This is generally why having a boy is more preferred than a girl when giving birth. The real and final home for a woman was her husband's not her own family's. The character of 嫁 just tells you that a woman hadn't returned to her permanent setting place or had a real home until she got married to a man.
