How English words are formed

HISTORY
top
Over the centuries, the English language has been influenced by a number of other languages. In particular, many words were taken from Greek and Latin.

The languages of Greek and Latin are known as the Western Classical Languages and have had a major impact on the English language. It is helpful to know something of the structure of Greek and Latin, to appreciate how English uses these languages for the composition of its vocabulary.

INFLECTIONS

Greek and Latin are called inflecting languages. 'Inflecting' means that the meaning of words are changed by the addition of prefixes and suffixes. Prefixes are added to the beginnings of words, while suffixes are added to the ends of words.

For example:

describe description

The underlined part of the above words is called the 'root.' The Latin root scrib (with the alternative form scrip) means 'to write.'

How would you divide the following words into parts?

production
reproduction
reproductive
productivity

COMMON ROOTS

Knowing some high frequency roots will help you to guess the meaning of new words in English. It is useful to try to learn an example word for each root. For instance, if you wanted to remember that the root spect means 'to look', you might commit to memory the word 'spectator' meaning 'someone who looks.'

In the following table you can see some common roots. For each root an example word is given. You might be able to think of another example word.

Root Example Word
bio = life biology
ced-, ceed, cess = go proceed
dict = to say predict
duc-, duct- = lead conductor
fer-, lat- = carry transfer
flu-, flux- = flow influx
graph = write, draw autograph

PREFIXES

Just as it is useful to learn some common roots, it is also very good to know some high frequency prefixes. Remember, these are added to the beginnings of words and usually change the meaning of the base word.

Prefix Example Word
ab-, a- = away, from abduct
ad-, ac-, a- = to, towards admit
circum- = around circumspect

SUFFIXES

As you might have guessed, your knowledge of the formation of English words would not be complete without some awareness of common suffixes. Remember, suffixes are added to the ends of words and usually change the function of a word. For example, the addition of the suffix -ity changes an adjective to a noun.
