Week 9

The teacher revises the previous lesson and introduces the new topic by defining negative prefixes and gives examples

Negative prefixes are word parts added to the beginning of a base word to create a new word with the opposite or negative meaning. They indicate negation, opposition, or reversal of the root word's meaning.

Examples of Negative Prefixes:

1.   Un-: Changes the meaning to "not" or "the opposite of."

o    Example: Unhappy (not happy), Unlikely (not likely).

2.   In-: Implies "not" or "without."

o    Example: Inaccurate (not accurate), Invisible (not visible).

o    Note: Variations include "Im-" (before words starting with "p" or "m"), "Il-" (before "l"), and "Ir-" (before "r").

3.   Dis-: Indicates opposition or reversal.

o    Example: Disagree (not agree), Disappear (to stop being visible).

4.   Non-: Means "not" or "without."

o    Example: Nonsense (without sense), Nonexistent (not existing).

5.   Im-: Used to mean "not" before certain consonants (p, b, m).

o    Example: Impossible (not possible), Immobile (not mobile).
