The head is the central element that determines the grammatical properties of the entire unit, while the dependents modify or complement the head. Complex heads can be found in various linguistic structures, such as noun phrases, verb phrases, and compound words. For example, in the compound word "blackbird," "bird" is the head and "black" is its dependent, forming a complex head. **
