An educational worksheet teaching negative prefixes in English, featuring examples and exercises to help students understand how prefixes modify word meanings.

The image you provided is about negative prefixes in English. Negative prefixes are used to give words (nouns, verbs, or adjectives) a negative meaning. The most common ones include:

- un-
- in-
- im-
- il-
- ir-
- dis-
- a-
- de-
- non-

Key Points from the Image:

1. Rules for Using "in-":
- It changes to "im-" before adjectives beginning with m and p.
- It changes to "il-" before adjectives beginning with l.
- It changes to "ir-" before adjectives beginning with r.

2. Other Prefixes:
- Most other prefixes have a Latin or Greek origin and are typically followed by words derived from those languages.
- Mis- is the only prefix of purely English origin and is mostly attached to verbs, but it can also combine with non-native words.
- When new words are coined, non- is often preferred (e.g., non-smoker, non-stop).

3. Examples Provided:
- Words are categorized under different prefixes like un-, in-, im-, il-, ir-, dis-, a-, de-, and non-.
- Some examples include:
- Un-: unhappy, unkind, unlucky, unpack, unpredictable, unarmed, unjust, unfortunate, unacceptable, unconscious, untrue, unsteady, unpack, unlock.
- In-: informal, injustice, invisible, inadequate, independent, insufficient, impatient, incapable, inaccurate, illegitimate, illegal.
- Im-: imperfect, immaturity, immobility, immodest, impolite, impersonal, impractical, illegality, illogical, illegal.
- Il-: dislike, discomfort, disbelief, dishonest, disloyalty, disapproval, dissatisfaction, discontent, disrespect, disobedience.
- Ir-: irregular, irresponsible, impatient, impolite, impersonal, impractical, illegality, illogical, illegal.
- Dis-: disagree, disadvantage, disappear, disobey, disappoint, disapprove, disbelieve, discontinue, disengage, disqualify.
- A-: abnormal, atheist, asymmetric, anaesthetic, antisocial, antacid.
- De-: defrost, detach, decay, declassify, decode.
