Roots and Affixes in Morphology

• Affixes and roots are fundamental to morphology, which is the study of word structure.
• Understanding affixes and roots is essential for vocabulary building, reading comprehension, and linguistic analysis.

Roots

• A root is the core of a word, and it carries the primary meaning.
• Roots serve as the base form to which affixes are attached.
• Roots can be classified as either free or bound.

Free Roots

• Free roots can stand alone as independent words
• Examples include "act" in "action," "cat," and "house”.

Bound Roots

• Bound roots cannot stand alone; they must be attached to affixes.
• Examples include "ject" in "reject," "inject," and "project", also "cran" in "cranberry."

Affixes

• Affixes are word elements attached to roots to modify their meaning or grammatical function.
• Common affix types include prefixes, suffixes, infixes, and circumfixes.

Prefixes

• Prefixes are added to the beginning of a root.
• Typically, prefixes alter the meaning of the root to which they are attached.
• Examples include "un-" in "unhappy," "re-" in "rewrite," "pre-" in "prehistoric," "dis-" in "disagree," and "anti-" in "antivirus."
• "un-" often indicates negation or reversal.
• "re-" often indicates repetition or renewal.
• "pre-" often indicates before or prior.
• "dis-" often indicates negation or separation.
• "anti-" often indicates opposition or prevention.

Suffixes

• Suffixes are added to the end of a root.
• Suffixes can change the meaning or grammatical category of the root.
• Examples include "-ness" in "happiness," "-ly" in "quickly," "-er" in "worker," "-ing" in "walking," "-ed" in "walked," and "-tion" in "action."
• "-ness" typically forms nouns indicating a state or quality.
• "-ly" typically forms adverbs indicating a manner.
• "-er" typically forms nouns indicating a person or thing that performs an action.
• "-ing" typically forms present participles or gerunds indicating an ongoing action.
• "-ed" typically forms past tense verbs or adjectives indicating a completed action.
• "-tion" typically forms nouns indicating an action or process.

Infixes

• Infixes are inserted within the root of a word.
• English does not commonly use infixes.
• An example from another language is the infix "-um-" in the Tagalog word "sulat" (write), which becomes "sumulat" (wrote).

Circumfixes

• Circumfixes are attached both at the beginning and the end of the root.
• English does not commonly employ circumfixes.
• An example from another language is the German prefix "ge-" and suffix "-t" in "gespielt" (played), derived from the root "spiel" (play).

Derivational Affixes

• Derivational affixes create new words from existing ones.
• These can change the meaning or the grammatical category of the word.
• Adding "-ness" to "happy" creates "happiness" (adjective to noun), while adding "un-" to "kind" creates "unkind" (adjective to adjective).
• These affixes can significantly alter a word's meaning or usage.

Inflectional Affixes

• Inflectional affixes modify a word to express grammatical information.
• They do not change the core meaning or grammatical category of the word.
• English has eight inflectional affixes:
  • "-s" (3rd person singular present tense: "he walks")
  • "-ed" (past tense: "he walked")
  • "-ing" (present participle: "he is walking")
  • "-en" or "-ed" (past participle: "he has eaten/walked")
  • "-s" (plural: "cats")
  • "-'s" (possessive: "cat's")
  • "-er" (comparative: "faster")
  • "-est" (superlative: "fastest")
• These affixes ensure grammatical correctness and clarity.

Morphological Analysis

• Morphological analysis involves breaking down words into their constituent morphemes, i.e., roots and affixes.
• It helps in understanding the meaning and structure of complex words.
• For example, "unbreakable" can be analyzed as "un-" (prefix) + "break" (root) + "-able" (suffix).
• This analysis reveals the word means "not able to be broken."

Allomorphs

• Allomorphs are variant forms of a morpheme.
• The choice of allomorph depends on the phonetic environment.
• The plural morpheme in English has three common allomorphs:
  • /-s/ as in "cats"
  • /-z/ as in "dogs"
  • /-ɪz/ as in "buses"
• Selection of which allomorph to use is governed by phonological rules.

Importance in Vocabulary Building

• Understanding roots and affixes significantly enhances vocabulary acquisition.
• By recognizing common roots and affixes, learners can deduce the meaning of unfamiliar words.
• Knowing that "bene" means "good" helps in understanding words like "benefit," "benevolent," and "beneficial."

Examples of Common Roots

• "aud" means hear (e.g., "audible," "audience," "auditorium").
• "bio" means life (e.g., "biology," "biography," "biopsy").
• "chron" means time (e.g., "chronological," "chronicle," "synchronize").
• "dic/dict" means speak (e.g., "dictate," "diction," "predict").
• "graph" means write (e.g., "graphic," "autograph," "biography").
• "log" means word, study (e.g., "logic," "biology," "dialogue").
• "meter" means measure (e.g., "meter," "thermometer," "perimeter").
• "path" means feeling (e.g., "sympathy," "empathy," "apathy").
• "phon" means sound (e.g., "telephone," "phonics," "symphony").
• "vis/vid" means see (e.g., "visible," "video," "evidence").
• "terr" means earth (e.g. terrain, territory, terrestrial)
• "port" means carry (e.g. transport, export, import)

• "ambi-" means both (e.g., "ambidextrous," "ambivalent").
• "circum-" means around (e.g., "circumnavigate," "circumference").
• "co-, con-" mean with, together (e.g., "cooperate," "convene").
• "contra-, counter-" mean against (e.g., "contradict," "counteract").
• "de-" means down, away from (e.g., "descend," "deactivate").
• "extra-" means beyond, outside (e.g., "extraordinary," "extracurricular").
• "inter-" means between (e.g., "interact," "interstate").
• "intra-" means within (e.g., "intramural," "intravenous").
• "multi-" means many (e.g., "multimedia," "multicultural").
• "post-" means after (e.g. post-war, post-mortem)

Practical Applications

• Analyzing words into roots and affixes enhances reading comprehension.
• It aids in deciphering complex and technical vocabulary.
• Knowledge of morphology is crucial in fields like linguistics, education, and computational linguistics.
• It helps in understanding language evolution and word formation processes.
