Morphology (linguistics) Study Guide

📖 Core Concepts Morphology – study of word structure, how words are built and related. Morpheme – smallest meaning‑bearing unit; can be a root (stand‑alone) or an affix (bound). Lexeme – abstract entry in the mental dictionary; set of word‑forms sharing a core meaning (e.g., EAT). Word‑form – concrete surface form that appears in speech/writing (e.g., eats, eating). Inflection – rule‑based alteration of a lexeme’s form to express grammatical categories (tense, number, case) without changing its syntactic class. Word‑formation – processes that create new lexemes (derivation, compounding, borrowing, etc.) and often shift grammatical category. Derivation vs. Compounding – derivation adds bound affixes (dependent → independent); compounding joins two free words (dog catcher). Paradigm – complete set of inflected forms for one lexeme, organized by categories (tense, number, gender, case…). Morphosyntax – interaction of morphology and syntax; includes agreement (matching features) and government (case‑governing relations). Allomorphy – a single morphological function realized by multiple phonological variants (e.g., plural ‑s vs ‑es). Morphological Typology – classification of languages by how they encode grammatical information: isolating, agglutinative, fusional (also called inflectional). Synthetic vs. Analytic – synthetic languages rely heavily on morphology; analytic languages rely on separate syntactic words. --- 📌 Must Remember Inflection never changes lexical category; word‑formation often does. Derivation = bound affix + new lexeme; Compounding = two free words → new lexeme. Isolating → one morpheme/word; Agglutinative → many “one‑function” morphemes; Fusional → one morpheme = several functions. Agreement = feature matching (e.g., subject‑verb number). Allomorphy is phonological variation of the same morpheme, not a different morpheme. Lexical morphology = derivation + compounding (lexicon‑level processes). Morpheme‑based model = item‑and‑arrangement (word = ordered morpheme slots). Lexeme‑based model = stems + rules (inflectional vs. derivational). --- 🔄 Key Processes Inflectional Paradigm Generation Identify lexeme → list relevant grammatical categories → apply language‑specific inflectional rules to produce each cell (e.g., dog → dogs, dog’s). Derivation Start with base lexeme → attach bound affix → check for category shift (e.g., depend (verb) + ‑ent → dependent (noun/adjective)). Compounding Select two free lexical items → combine in language‑specific order → optionally apply phonological adjustments (e.g., dog + catcher → dog catcher). Other Word‑Formation Clipping: truncate a word (advertisement → ad). Blending: merge parts of two words (smoke + fog → smog). Acronym formation: take initial letters (NATO). Borrowing: adopt a foreign form (café). Coinage: create a brand‑new term (google). Allomorph Selection Choose appropriate allomorph based on phonological environment (e.g., plural ‑s after voiced sounds, ‑es after sibilants). --- 🔍 Key Comparisons Inflection vs. Word‑formation Inflection: same lexeme, same category, grammatical meaning. Word‑formation: new lexeme, often new category, lexical meaning. Derivation vs. Compounding Derivation: bound affix + existing lexeme → new lexeme. Compounding: two independent words → new lexeme. Isolating vs. Agglutinative vs. Fusional Isolating: 1 morpheme/word, little affixation. Agglutinative: many clear‑cut affixes, each ≈ one grammatical feature. Fusional: single affix packs multiple features, morpheme boundaries blurred. Morpheme‑Based vs. Lexeme‑Based Models Morpheme‑Based: view word as a string of morphemes (slots). Lexeme‑Based: view word as stem + rule‑driven transformations. --- ⚠️ Common Misunderstandings “All affixes are derivational.” – Many affixes are inflectional (e.g., ‑s for plural). “Compounds are always written as one word.” – Languages differ; some use hyphens or spaces. “Agglutinative = synthetic.” – Agglutinative is a subtype of synthetic; synthetic also includes fusional languages. “Allomorphs are separate morphemes.” – They are alternative phonological realizations of the same morpheme. “Morphology only concerns meaning.” – It also encodes grammatical relations (case, agreement). --- 🧠 Mental Models / Intuition “Morpheme = Lego brick.” – Small, meaning‑bearing piece; you can snap them together (compounding) or stick a sticker (affix). “Paradigm = a spreadsheet.” – Rows = grammatical categories; columns = resulting word‑forms. “Typology as a spectrum.” – Visualize a line from “no bricks” (isolating) → “many distinct bricks” (agglutinative) → “blended bricks” (fusional). “Allomorphy = pronunciation variants of the same rule.” – Like “/k/ vs /g/” after different vowels, but the underlying rule is unchanged. --- 🚩 Exceptions & Edge Cases Fusional languages may still show clear morpheme boundaries in some affixes (e.g., Russian ‑ov for genitive singular). Some derivational affixes do not change category (e.g., ‑ness creates a noun from an adjective, but ‑ly creates an adverb from an adjective). Borrowed words can retain original morphology (e.g., café keeps French stress pattern). Clipping can create new lexical items that become independent lexemes (e.g., lab from laboratory). --- 📍 When to Use Which Identify the task: If the question asks for the grammatical variation of the same word → use inflectional paradigm. If it asks for a new word meaning “related to X” → use derivational affix. Typology clue: Isolating language question → expect minimal affixation; focus on word order. Agglutinative language question → count morphemes, each maps to a distinct feature. Fusional language question → one affix may encode several features; look for the most inclusive rule. Allomorph selection: Check phonological environment (voicing, sibilants) to choose correct allomorph. --- 👀 Patterns to Recognize “+‑s / +‑es” pattern for English plurals → allomorphy cue. “Root + Derivational Affix = New Lexeme” → derivation pattern. “Stem + Multiple Clear‑Cut Affixes” → agglutinative pattern (e.g., Turkish ev‑ler‑imiz‑den “from our houses”). “Single Affix = Multiple Features” → fusional pattern (e.g., Latin ‑am = accusative + feminine singular). “Word‑form set aligned by tense, number, case” → paradigm pattern. --- 🗂️ Exam Traps Choosing “inflection” for a derivational process because both add affixes. Remember: inflection ≠ category change. Assuming all compounds are written as one word; some languages use hyphens or spaces. Mixing up agglutinative vs. fusional: a language with many affixes is not automatically agglutinative if those affixes fuse multiple meanings. Allomorph vs. new morpheme: seeing ‑s vs ‑es and thinking they are separate morphemes; they are allomorphs of the plural morpheme. Treating “synthetic” as synonymous with “fusional.” Synthetic includes both agglutinative and fusional; analytic is the opposite. ---
