Specifies a key that that is only partially unique. Used for weak entities.
When a database table has a key which consists of more than one field, a partial key refers to any one of those fields.

When a database table has a key which consists of more than one field, a partial key refers to any one of those fields.
The difference is that partial dependency is when a database's attribute is only partially dependent on the primary key. Fully functional dependency is when the attribute is entirely dependent on the key.

Found a nice explanation here: http://www.e-consultancy.com/knowledge/glossary/1163/partial-functional-dependency.html In database terminology, a partial functional dependency occurs when the value in a non-key attribute of a table is dependent on the value of some part of the table's primary key (but not all of it).
Partial dependency occurs in a database when a non-prime attribute is dependent on only a part of a composite primary key, rather than on the whole key. For example, in a table with a composite primary key consisting of StudentID and CourseID, if the attribute InstructorName is dependent only on CourseID, then this is a partial dependency. It indicates that the design can be improved by normalizing the database to eliminate such dependencies.

A partial hepatectomy is a partial removal of the liver.
A partial quote is a segment of a larger statement or text that captures a specific idea or phrase without including the entire context. For example, if the original statement is, "The quick brown fox jumps over the lazy dog," a partial quote could be, "the quick brown fox." Partial quotes are often used to highlight a key point or to support an argument while omitting less relevant information.
Partial positive and partial negative charges form due to the unequal sharing of electrons in a covalent bond. When two atoms with different electronegativities bond, the atom with higher electronegativity attracts the shared electrons more strongly, resulting in a slight negative charge on that atom and a slight positive charge on the other. This difference in charge distribution creates a dipole, which is a key characteristic of polar molecules.
