Prefixes and sufixes

CREATING NEW WORDS

Did you know that you can redo something and if you're not happy with it, you can undo it?

WHAT DO THESE GROUP OF LETTERS MEAN?

Re: means again. So if you redo something, you do it again. Ex: Return, rediscover, reunite. Un: It's an opposite. So if you undo something, you reverse what you have done. Ex: Unfinished, unfriendy, unknown.

According to this example, what does the prefix "DIS" mean?

agree? like? allow? appear?

DIS

DIS also means "no" or "reversal". Ex: The engineer disallowed the proposal.

SO WHAT IS A PREFIX?

A prefix is a group of letters that you can add to the beginning of a root word* to change the meaning of the word. For example, anti + biotic = antibiotic. *A root word stands on its own as a word but you can make new words from it by adding beginnings (prefixes) and endings (suffixes). For example, ‘geologist’ is composed by the prefix ‘Geo’ which means "earth" qnd by the suffix "ist" which means a person or an object that does a specified action. "GEOLOGIST."

THE MOST COMMON PREFIXES

THE IMPORTANCE IN SCIENCE

In sicence there are too many composed words and knowing prefixes and suffixes can help you to deduce the meaning of new concepts. Here there are some examples:

SOME EXAMPLES IN SCIENCE

EPI: Epidemic, epicenter, epidermis, epidural. ANTI: -Against- Antibiotic, antidote. ENDO: Endocrine, endoderm, endorphin. MONO: Mononucleosis, monotheism, monohydrate. PERI: Periphery, periscope, perimeter.

HOW TO TRANSFORM THE WORD "HAPPY" INTO A NOUN?

By adding the suffix: "ness", happy, passes from being an adjective to be a noun. Ex: "I am happy". / "Happiness is what I feel when I eat pizza". Here are two more adjectives that can be transformed into nouns: "Sad" and "tired": "Sadness and tiredness".

so what are suffixes?

A suffix is a letter or a group of letters that is usually attached to the end of a word to form a new word, as well as alter the way it functions grammatically. Depending on whether it is a noun, verb, adjective or adverb, a different suffix would be required. For example, the verb read can be altered to become the noun: "reader" by adding the suffix ­-"er". The same verb can also be turned into the adjective: "readable" by adding the suffix –able.

WHAT IS THE DIFFERENCE BETWEEN PREFIXES AND SUFFIXES?

In simplistic terms prefixes change the meaning of words, and suffixes change their form (including plural, tense, comparative, and part of speech). Some of the most common suffixes are:

some examples in science

Itis: Appendicitis, arthritis, bronchitis, cerebritis. Pathy: Biopathy, immunopathy, neuropathy. Logy: Archaeology, anthropology, paleontology. Lysis: Analysis, catalysis, dialysis. For pain: algia, -cardia, -emia, -itis, -lysis, -oma, -osis, -pathy. Ex: Fibromyalgia, neuralgia, hypoglycemia, arthritis, paralysis, glaucoma, proctosis, neuropathy.

SOME INTERESTING TIPS:

For prefixes: They are typically used to negate, counter, or intensify the meaning of a word. The majority of prefixes are used before a noun or adjective, while some are used before a verb. Here are some of the ways you can use prefixes in a word.

To Increase Or Decrease The Strength Of A Word: Over-, Under-, Up-, Down-, and hyper- denote the degree, quality, quantity, or a trend. Examples are: Rate/ overrate Perform / underperform Scale/ upscale Fall / downfall

To Counter The Meaning Of A Word: Prefixes like im-, anti-, de-, dis-, un-, and non- are used to mean opposite of a word. Examples include: Moral/immoral War/ antiwar Centralize / decentralize Official/ unofficial Political/ non-Political Agree/ disagree
