• Common Prefixes:
  • "re-" (again): e.g., "redo".
  • "dis-" (not/opposite of): e.g., "disagree".

Usage In Vocabulary

• Prefixes are added to the start of a word to change its meaning.
• Functionality includes altering the part of speech; for example, "happy" becomes "unhappy" through the addition of "un-."
• Prefixes can generate antonyms, such as "legal" becoming "illegal" by using the prefix "il-."
• Prefixes can denote quantity, position, or time. Examples include "bi-" indicating two, "pre-" meaning before, and "sub-" signifying under.
• Common prefixes include:
  • "re-" meaning again, as in "redo."
  • "dis-" indicating not or opposite of, such as "disagree."
  • "trans-" meaning across, exemplified in "transport."
  • "anti-" signifying against, seen in "antibiotic."

Meaning Of Prefixes

• Prefixes can be categorized based on their function:
  • Negation: Includes prefixes like "un-", "non-", and "dis-" which signal the opposite of the root word's meaning.
  • Time/Order: Prefixes such as "pre-" (before) and "post-" (after) relate to temporal context.
  • Number: Examples are "mono-" (one), "bi-" (two), and "tri-" (three) which indicate quantity.
  • Position or Place: Prefixes like "sub-" (under) and "super-" (over) describe location or hierarchical relationships.
• Forming a new word involves combining a prefix with a base word to create a modified meaning, such as "submarine" where "sub-" means under and "marine" refers to the sea.

Usage In Vocabulary

• Prefixes modify the meanings of base words by being added to the beginning.
• They can change a word's part of speech; for example, adding "un-" to "happy" forms "unhappy," maintaining it as an adjective.
• Prefixes can create antonyms, such as "il-" transforming "legal" into "illegal."
• Certain prefixes denote quantity, position, or time; "bi-" indicates two, "pre-" means before, and "sub-" indicates under.

Common Prefixes

• "re-" signifies repetition, as seen in "redo."
• "dis-" denotes negation or opposition, as in "disagree."
• "trans-" refers to movement across; for example, "transport."
• "anti-" means against, used in terms like "antibiotic."

Meaning Of Prefixes

• Prefixes can be categorized based on their function:
  • Negation: Includes prefixes like "un-", "non-", and "dis-" that express the opposite meaning.
  • Time/Order: Prefixes such as "pre-" (before) and "post-" (after) indicate timing of events.
  • Number: Numeric prefixes like "mono-" (one), "bi-" (two), and "tri-" (three) describe quantities.
  • Position or Place: "sub-" (under) and "super-" (over) convey location or hierarchical status.

Formation

• The structure often follows: Prefix + Base word results in a new word with a modified meaning.
• An example of this formation is "submarine," where "sub-" (under) combined with "marine" creates a term meaning under the sea.

Additional Context

• The prefix "uni-" from "uniform" indicates singularity, suggesting a single style or design that is consistent across members of a group (e.g., employees).
