Ch. 4 Structural Relations Flashcards
Branch
A line connecting two parts of a tree
Node
The end of the branch
Label
The name given to a node
(Proper) Domination
Node A dominates node B if and only if A is higher up in the tree than B and if you can trace a branch from A to B going only downwards.
Immediately Dominate
Node A immediately dominates node B if there is no intervening node G that is dominated by A, but dominates B. (In other words, A is the first node that dominates B.)
Mother
A is the mother of B if A immediately dominates B.
Daughter
B is the daughter of A if B is immediately dominated by A.
Sisters
Two nodes that share the same mother
Root Node
The node that dominates everything, but is dominated by nothing. (The node that is no node’s daughter.)
Terminal Node
A node that dominates nothing. (A node that is not a mother.)
Non-Terminal Node
A node that dominates something. (A node that is a mother).
Exhaustive Domination
Node A exhaustively dominates a set of terminal nodes provided it dominates all the members of the set and there is no terminal node G dominated by A that is not a member of the set.
Constituent
A set of terminal nodes exhaustively dominated by a particular node
Constituent of
A is a constituent of B if and only if B dominates A.
Immediate Constituent of
A is a immediate constituent of B if and only if B immediately dominates A.
Sister Precedence
Node A sister-precedes node B if and only if both are immediately dominated by the same node, and A appears to the left of B.
Precedence
Node A precedes node B if and only if neither A dominates B nor B dominates A and A or some node dominating A sister-precedes B or some node dominating B.
No Crossing Branches Constraint
If node X precedes another node Y then X and all nodes dominated by X must precede Y and all nodes dominated by Y.
Immediate Precedence
A immediately precedes B if there is no node G that follows A but precedes B
C-Command (informal)
A node c-commands its sisters and all that daughters of its sisters
C-Command (formal)
Node A c-commands node B if every node dominating A also dominates B and neither A nor B dominates the other.
Symmetric C-Command
A symmetrically c-commands B if A c-commands B and B c-commands A.
Asymmetric C-command
A asymmetrically c-commands B if A c-commands B but B does not c-command A.
Government
Node A governs node B if A c-commands B, and there is no node G, where G is c-commanded by A and G c-commands B.
Phrase-Government
If A is a phrase, then the categories that count for G in the above definition must also be phrases
Head-Government
If A is a head (word), then the categories that count for G in the above definition must also be heads.
Subject
NP or CP daughter of Tp
Object of Preposition
NP daughter of PP
Oblique
Any NP/PP in the sentence that is not a subject, object of a preposition, or indirect object.
