NP movement in syntax refers to the phenomenon where a noun phrase (NP) is displaced from its original position in a sentence to a different position, often for reasons related to emphasis, focus, or grammatical requirements. This movement is commonly observed in languages with rich inflectional morphology and can occur in various structures, such as topicalization or wh-movement. For example, in the sentence "What did you eat?" the NP "what" moves to the front of the sentence, highlighting the object of the verb. NP movement is a key concept in generative grammar, helping to explain sentence structure and the relationships between elements in a sentence.
