Prefixes and Roots in Language

Prefixes

• Prefixes are morphemes (meaningful units of language) that are added to the beginning of a word to change its meaning.
• They often indicate a relationship to other words, such as indicating a location, time, or quantity.
• Examples:
  • un- (e.g., unhappy, undo) indicates negation or reversal
  • re- (e.g., rewrite, retell) indicates repetition or re-doing
  • pre- (e.g., prepare, predict) indicates before or in advance
  • pro- (e.g., progress, pronounce) indicates forward movement or forthright
  • anti- (e.g., antisocial, antibiotic) indicates against
  • super- (e.g., superlative, supermarket) indicates above, better or additional

Roots

• Roots are morphemes that are the core of a word, carrying the basic meaning.
• They can be Latin or Greek in origin.
• These provide the fundamental meaning, and affixes (prefixes & suffixes) modify the meaning.
• Examples:
  • aqua (Latin) – water (e.g., aquarium, aqueduct)
  • bio (Greek) – life (e.g., biology, biosphere)
  • graph (Greek) – write (e.g., photograph, autograph)
  • meter (Greek) – measure (e.g., thermometer, barometer)
  • ped (Latin) – child (e.g., pediatrician, orthopedic)

Suffixes

• Suffixes are morphemes that are added to the end of a word to change its meaning or grammatical function.
• They often indicate the part of speech (e.g., noun, verb, adjective).
• Examples:
  • -ness (e.g., happiness, kindness) turns an adjective into a noun
  • -er (e.g., teacher, baker) turns a verb into a noun
  • -ful (e.g., careful, beautiful) describes an adjective
  • -ing (e.g., running, reading) indicates a verb in progressive form
  • -ment (e.g., judgment, movement) turns a verb into a noun.
  • -ous (e.g., famous, dangerous) modifies an adjective or noun, sometimes representing a quality

Synonyms

• Synonyms are words that have similar meanings.
• They can be used interchangeably in many contexts, although subtle differences in connotation or usage might exist.
• Using synonyms can enhance language and vocabulary.
• Examples:
  • happy and joyful
  • big and large
  • small and tiny
  • good and excellent
  • sad and unhappy

Antonyms

• Antonyms are words that have opposite meanings.
• They are used to highlight contrasting concepts or ideas.
• Examples:
  • hot and cold
  • good and bad
  • big and small
  • up and down
  • fast and slow
