Agreement

The relationships between words are based on agreement. Words have to agree in the following ways:

number singular/plural person first/second/third person tense past/present/future gender natural (male/female)/grammatical voice active/passive voice

Structural Analysis

Structural analysis helps to investigate the distribution of forms in a language. For example: many English sentences follow and SVO pattern:

Subject Verb Object [The earthquake] [shook] [the house].

Different languages prefer different word order. Here is Japanese:

Subject Object Verb [Masuda-ga] [tegami-o] [kakimasu]

Masuda letter write. (Masude writes a letter)

Test Frames

Examples:

The_____________ gets wet when it rains.

_____________ melt in the summer heat.

Have you seen ___________.

The old building by the library ________________.

Ø  Forms that fit into the same test-frame likely belong to the same grammatical category [noun/noun phrase/verb phrase/etc.]

Constituent Analysis

•  Small constituents (articles, nouns, etc) combine to form larger constituents:

Ø  noun phrases verb phrases prepositional phrases clauses sentences

And speakers arrange these constituents according to the conventions of the grammatical rules of the language they are speaking.

;{prescriptivism & descriptivism};

Ø  Prescriptive grammarians are interested in formulating grammatical and usage rules that should be followed by speakers of the language.

Ø Descriptive linguists use structural analysis to help them describe the structural rules as they are applied by speakers of a language.
