X-bar theory uses the rule VP → V NP to build verb phrases. Minimalist syntax uses Merge to build the same structure. What is the key theoretical advantage of the Merge approach?
AMerge is computationally faster, making sentence processing more efficient in the brain
BMerge is a single category-independent operation that replaces dozens of category-specific phrase structure rules, reducing the complexity of the grammar the language faculty must contain
CMerge explicitly specifies the linear order of constituents, solving cross-linguistic variation in word order
DMerge applies only to lexical categories (nouns, verbs), while X-bar theory also handles functional categories
The theoretical gain from Merge is explanatory parsimony. Instead of VP → V NP, NP → Det N, CP → C IP, and dozens of other category-specific rules, the minimalist program posits one operation: combine any two syntactic objects. The reduction in required grammatical machinery is the point. Option A is not the theoretical claim — Merge is about the grammar's representational complexity, not processing speed. Option C is wrong: Merge deliberately does NOT specify linear order (that is handled separately in Spell-Out/linearization). Option D is wrong — Merge applies uniformly across all syntactic categories, lexical and functional.
Question 2 Multiple Choice
A wh-question like 'What did John eat?' features 'what' at the front of the sentence rather than after the verb where it is interpreted. In minimalist syntax, this is analyzed as:
AA special morphological rule that relocates interrogative pronouns to sentence-initial position
BInternal Merge: 'what' is first introduced as the object of 'eat' by External Merge, and then merged again with the root of the clause, leaving a copy in its original position
CExternal Merge applied twice: 'what' merges with the verb phrase and then separately merges with the complementizer from outside the structure
DA language-specific parametric exception permitted in English but not in other languages
Internal Merge takes an element already inside a syntactic structure and merges it again with the root of that structure, producing a copy at the original position. 'What' is first introduced as the object of 'eat' by External Merge; then Internal Merge takes it and merges it with the CP root. This reanalyzes traditional 'movement' as simply Merge applying to an already-present element. The key theoretical achievement: question formation, passivization, and topicalization — previously described by separate movement rules — are all unified as instances of the same operation. Option C would introduce 'what' twice from outside the structure, which is wrong. Option D is incorrect — Internal Merge is the standard universal analysis.
Question 3 True / False
Merge generates infinite linguistic expressions from finite means because any syntactic object produced by Merge can serve as an input to a further Merge operation.
TTrue
FFalse
Answer: True
Recursion is the source of infinity. Merge(α, β) produces a new syntactic object that is itself a valid input to Merge. There is no principled upper limit — sentences within sentences, relative clauses modifying relative clauses, and so on can be nested indefinitely. This recursive self-embedding generates an unbounded set of possible sentences from a finite vocabulary and a single operation, without any additional machinery. It derives, rather than stipulates, one of the most distinctive properties of human language.
Question 4 True / False
Merge specifies the linear order of the two elements it combines, determining which one precedes the other in the spoken or written output.
TTrue
FFalse
Answer: False
Merge is defined as combining two objects into a set: {α, β}. Sets are unordered — the definition contains no specification of which element precedes the other. Linear order (surface word order) is determined by a separate mapping from hierarchical syntactic structure to phonological form, often called Linearization or Spell-Out. This separation is theoretically important: it explains how languages with different surface word orders (SVO English vs. SOV Japanese vs. VOS Malagasy) can share the same underlying hierarchical structures built by the same Merge operation, differing only in how they linearize that structure for pronunciation.
Question 5 Short Answer
How does the minimalist program's reduction of all syntactic structure-building to a single Merge operation improve on X-bar theory? What theoretical work does this simplification accomplish?
Think about your answer, then reveal below.
Model answer: X-bar theory required many category-specific phrase structure rules plus a separate Move operation for displacement phenomena like wh-questions and passives. Merge replaces all phrase structure rules with one operation (External Merge) and reanalyzes movement as Internal Merge — the same operation applied to an element already in the structure. This eliminates the distinction between structure-building and movement as separate cognitive capacities, showing they are one computation. The simplification also focuses cross-linguistic variation on the lexicon rather than on grammatical rules.
The deeper theoretical achievement is explanatory unification. In X-bar theory, you needed to stipulate rules AND a separate movement operation with its own conditions and filters. In minimalism, both fall out of a single recursive operation that takes any two objects and combines them. The only question is whether the objects being combined are fresh (External) or already present in the structure (Internal). This reduction shifts the research question from 'which rules does this language have?' to 'how does universal Merge interact with language-specific lexical properties?' — a more tractable and principled inquiry.
