Dependency Grammar aims to capture the syntactic dependencies between words in a sentence, rather than focusing on hierarchical structures or grammatical functions.

Head-Driven Phrase Structure is based on the idea that each phrase has a head, which is the most important word in the phrase and determines its syntactic properties.

In Dependency Grammar, the head governs the dependent, meaning that the head determines the syntactic properties of the dependent.

In Head-Driven Phrase Structure, the head determines the syntactic category of the phrase, such as noun phrase, verb phrase, or prepositional phrase.

Subject-Verb, Verb-Object, Noun-Adjective, and Adverb-Verb are all common types of dependency relations in Dependency Grammar.

In Head-Driven Phrase Structure, the head governs the complement, meaning that the head determines the syntactic properties of the complement.

The primary difference between Dependency Grammar and Phrase Structure Grammar is that Dependency Grammar represents the relationships between words in a sentence, while Phrase Structure Grammar represents the hierarchical structure of a sentence.

Noun, Verb, Adjective, and Preposition are all common types of heads in Head-Driven Phrase Structure.

In Dependency Grammar, a word that has no head is called a root.

Noun Phrase, Verb Phrase, Adjective Phrase, and Prepositional Phrase are all common types of complements in Head-Driven Phrase Structure.

In Dependency Grammar, a word that modifies a head is called a modifier.

Subject-Verb, Verb-Object, Noun-Adjective, and Adverb-Verb are all common types of dependency relations in Head-Driven Phrase Structure.

In Dependency Grammar, the relationship between a head and its dependent is called dependency.

Noun, Verb, Adjective, and Preposition are all common types of heads in Dependency Grammar.

In Head-Driven Phrase Structure, the relationship between a head and its complement is called government.
