Тема: Види префіксів в англійській мові

1. Presentation of new material

T.: Now, let's learn some new concepts on the topic.

I'll give you the cards (card#1) . You have to read and study the rules.

• A prefix is a letter or a group of letters attached to the beginning of a word that partly indicates its meaning. For example, the word prefix itself begins with a prefix--pre-, which generally means "before."
• Understanding the meanings of the common prefixes can help us deduce the meanings of new words that we encounter. But be careful: some prefixes (such as in-) have more than one meaning (in this example, "not" and "into").

Adjectives in English formed with prefixes:

• A prefix is a particle we add in front of a word, usually to express negative meaning:

un- (unlucky)

in- (invincible)

il- (illegal)

dis- (disproportional)

ir- (irrelevant)

im- (improper)

• Other prefixes modify the meaning of the word but do not form negative meaning:

pre- (pre-emptive)

hyper- (hyperactive)

Verbs in English formed with prefixes:

• Prefixes DE, DIS, DI

The prefixes DE, DIS, DI have similar meanings and are found in verbs and their derivatives. Most often, language learners confuse the prefixes DE and DI, which are similar in meaning and have the same pronunciation [di]. (In some cases, DE is pronounced as [de], and DI is pronounced as [dai].)

There are no rules that could help us to choose among these prefixes. Arrange the words with these prefixes in three columns on a page and learn them by comparing their meaning, spelling and pronunciation.

• Prefix DE

The prefix DE is found in verbs and their derivatives. It has several meanings, such as removal, separation, negation, descent, reverse action.

2. Writing
