Answer:
The context where our communication takes place defines meaning
Step-by-step explanation:
"Identity" of a person defines a person. Each person or each race or group of people have their own identities.
At home where Alliyah wears a modest dress and also wears a hijab makes an identity of herself and thus it make sense complete at home because people at home is aware of her clothes styles. But outside, people's perception about her dress may be different and thus has different views regarding her dress and hijab.
Thus the context of a particular identity is important and it carries different meanings in different situations.
