    Why do we say tree diagrams are more advantageous and informative than linear structure in analyzing the constituent relationship among linguistic elements Support your statement with examples?
    In addition to revealing a linear order,a constituent structure tree has a hierarchical structure that groups words into structural constituents and shows the syntactic category of each structural constituent,and consequently is believed to most truthfully illustrate the constituent relationship among linguistic elements.
    For example.the phrase “ the old men and women” may have two interpretations i.e. the adjective “old”may modify the noun “men” or the following two nouns “men and women”.Linear order analysis cannot tell this difference.so it is ambiguous. Whereas,the constituent or tree diagrams analysis can make this difference clear. So.we say tree diagrams are more advantageous and informative than linear structure analysis.(NP NP NP NP NP NP The old men and the women the old men and the old women.
