Non-configurational Language - Controversy With Dependency Grammars

Controversy With Dependency Grammars

The distinction between configurational and non-configurational languages can exist for phrase structure grammars only. Dependency grammars (DGs), since they lack a finite VP constituent altogether, do not acknowledge the distinction. In other words, all languages are non-configurational for DGs, even English, which all phrase structure grammars take for granted as a having a finite VP constituent. The point is illustrated with the following examples:

No structure will have a finite VP constituent.
No structure will have a finite VP constituent.

Phrase structure grammars almost unanimously assume that the finite VP in bold in the first sentence is a constituent. DGs, in contrast, do not see finite VPs as constituents. Both phrase structure grammars and DGs do, however, see non-finite VPs as constituents. The dependency structure of the example sentence is as follows:

Since the finite VP will have a finite VP constituent does not qualify as a subtree, it is not a constituent. What this means based upon the criterion of configurationality is that this dependency structure (like all dependency structures) is non-configurational. The distinction between configurational and non-configurational has hence disappeared entirely, all languages being non-configurational in the relevant sense. Note, however, that while the finite VP is not a constituent in the tree, the non-finite VP have a finite VP constituent is a constituent (because it qualifies as a subtree).

Dependency grammars point to the results of standard constituency tests as evidence that finite VP does not exist as a constituent While these tests deliver clear evidence for the existence of a non-finite VP constituent in English (and other languages), they do not do the same for finite VP.

Famous quotes containing the words controversy, dependency and/or grammars:

    And therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.
    Thomas Hobbes (1579–1688)

    The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.
    Shoshana Zuboff (b. 1951)

    A sure proportion of rogue and dunce finds its way into every school and requires a cruel share of time, and the gentle teacher, who wished to be a Providence to youth, is grown a martinet, sore with suspicions; knows as much vice as the judge of a police court, and his love of learning is lost in the routine of grammars and books of elements.
    Ralph Waldo Emerson (1803–1882)
