look up any word, like sex:
To kill an infant because they are female.
In some cultures males are more highly regarded and valued than females, which can cause female infanticide i.e. China 2007 maintains a rule, the One Child Policy, that you can only have one child, or be severely penalized for having more than one child.

Hindu's and Muslim's have a long tradition of females having to be married with a dowry, which can lead to poorer families committing female infanticide.
