Analyze semantic structure in a simple, declarative English sentence: X is a criminal. For this to be true, verify the components of the statement. The person must be X. The person must have committed a crime. The person has been identified as a criminal to other members of the public. If the sentence can be broken down into its individual parts and still retain its meaning, then it is true analytically.
Decode a semantic structure. Grammar, which is a type of semantic structure, encodes meaning on various levels. As an exercise, take a lexico-grammatical structure such as "for he's a jolly good fellow." Then jot down its possible ideational, interpersonal and textual meanings. Interpersonal meanings derive from using strategies of semantics like encouraging, arguing, advising, commanding, complimenting or questioning. Ideational meaning comes from the speaker and listener's thoughts or imagination of what a concept represents in the real world. This depends on how each person thinks of a "jolly good fellow" --- adult, male of a virtuous or entertaining character perhaps. The textual aspect, e.g., word choice and meaning, sound, syntax and punctuation, can also shape the listener's interpretation of the speaker's meaning.
Parse a sentence by identifying its component parts. The grammar of the sentence shows how it functions abstractly, separate from its particular meaning. For example, "The comediennes performed at the concert hall" contains a noun phrase (the comediennes) and a verb phrase (performed at the concert hall) that break down into smaller parts: verb (performed), feminine noun (comediennes), article (the) and preposition (at).
Create a syntactic tree and a semantic tree from the same sentence. Place the sentence on line one. Then draw lines underneath pointing to the noun (subject) at left, the auxiliary verb or prepositional phrase in the middle and the verb phrase (predicate) on the right.
