Linguistic Foundations
Talk: The act of a speaker using language in a specific circumstance. Phoneme: The minimum, meaningless abstract unit characterized by distinctive features that differentiate words. Sound: The concrete realization of a phoneme by an individual. Grapheme: The written reproduction of a phoneme.
Word Structure
Words are formed by the smallest meaningful units, known as monemes, which are divided into:
| Type | Description |
|---|---|
| Lexeme | Carries full, independent meaning. |
| Morpheme | Carries grammatical meaning. |
Morpheme Classifications
- Independent Morphemes: Function as words themselves (e.g., determiners and connectors).
- Dependent Morphemes: Linked directly to a lexeme:
- Flexive Morphemes: Provide purely grammatical meaning (e.g., number, gender, person).
- Derivative Morphemes: Qualify the meaning of the stem (prefixes, infixes, and suffixes).
Derivative morphemes are further categorized as significant (changing the lexeme into a different word) or appreciative (modifying the stem's nuance while keeping the word the same).
Word Classes and Formation
- Simple: Formed by a single stem and one or more flexive morphemes (e.g., tomatoes).
- Compound: Formed by two or more lexemes and corresponding flexive morphemes (e.g., bad-life).
- Derived: Consisting of a lexeme and one or more derivative morphemes (e.g., crop).
- Parasynthetic: Formed by two lexemes plus derivative morphemes (e.g., blush).
- Acronyms: Lexical units formed from initials (e.g., PP).
- Abbreviations: Formed by combining elements of multiple words (e.g., AIDS).
- Shortened Forms: Includes apocope (deletion of a sound at the end, e.g., cinemaógrafo to film) and apheresis (removal of a sound at the beginning, e.g., muchacha to chacha).
Semantic Relations
- Monosemy: One signifier corresponds to a single meaning.
- Synonymy: Different signifiers sharing the same meaning.
- Polysemy: One signifier associated with multiple meanings (e.g., human eye vs. lock eye).
- Homonymy: Originally separate words that evolved to share the same signifier.
- Homophones: Distinguished by writing.
- Homographs: Identical in sound and writing.
- Antonymy: Opposition of meanings:
- Pure Antonyms: Admit gradation.
- Complementarity: Absolute opposition where one excludes the other.
- Reciprocity: One term requires the existence of another.
- Hyperonymy: A word with a broader extension (hypernym) that includes others (hyponyms).
