أنت حرّ
You are free.
حرّرتك
I have freed you.
يا حرّ
O free person!
The language of freedom and manumission explicitly denotes the release of an enslaved person in the classical legal setting. Just as divorce vocabulary directly names divorce, the vocabulary of freedom directly names manumission.
A word explicit in one domain does not necessarily have the same direct meaning when transferred to another domain; such transfers belong to the preceding discussion of figurative usage.
