Determine the meanings of Greek and Latin roots

Key Notes :

A root is the core part of a word, carrying its fundamental meaning. It’s the base to which prefixes and suffixes are added. Greek and Latin roots are particularly prevalent in academic and technical vocabulary.

Key Concepts:

Root = Core meaning
Prefix = Added to the beginning
Suffix = Added to the end
Consider the word “biology“:

1. The root is bio, meaning “life.”
2. The suffix is -logy, meaning “the study of.”
Therefore, biology is the study of life.

Common Prefixes and Suffixes

Prefixes modify the beginning of a word, whereas suffixes modify the end of a word. Both prefixes and suffixes can change the meaning of a root significantly. For example:

Prefixes:

  • pre-: before (e.g., prewrite – to write before)
  • un-: not (e.g., unhappy – not happy)
  • re-: again (e.g., rewrite – to write again)
  • dis-: not, opposite of (e.g., disagree – not agree)
  • anti: against (e.g., antiwar – against war)

Suffixes:

  • -able: able to be (e.g., readable – able to be read)
  • -tion: act of (e.g., creation – act of creating)
  • -ly: in a manner (e.g., quickly – in a quick manner)
  • -ness: state of (e.g., happiness – state of being happy)
  • -ology: study of (e.g., biology – study of life)
