Transcript 14.1 prefix and sufixes

L/O: To examine ways in which we can analyze individual
words.
One of key concepts is Lexis – or word-choice
You may know this word, or you may be more familiar with the word
vocabulary.
However, “lexis” has two advantages.
It has an adjectival form – lexical.
And it has a slightly more specific meaning than
“vocabulary.” Lexis refers to “meaning” words rather
than grammatical – or “glue” – words. So, “people,”
“purple” are lexical; “in,” “might” are grammatical.
Today, we will begin to look at lexical morphology – or, the way
words, and their meanings, are built.
How can we begin to analyze individual words?
What could you say about the way the following words are ‘made’?
Root word: What is left when all
prefixes and suffixes are removed.
Also called the base word.

Key words

Root/Base word: what is left when all affixes are removed

Morpheme: The smallest component of a word that carries meaning

Affix: Morpheme attached before or after base word to change its
meaning

Prefix: Affix before a base word

Suffix: Affix after a base word




Inflectional suffix: Suffix that changes the grammar of a noun, verb,
adjective
Derivational suffix: Suffix that changes the changes the word class (e.g.
adjective to noun: slow – slowness.
Derivational prefix: Prefix that changes the meaning of a word – e.g.
pick/unpick
Absolute/Comparative/Superlative: Many adjectives have three forms.

Tall (absolute)

Taller (comparative – “taller than…”)

Tallest (superlative – the most tall)

How can we begin to analyze individual words?
Two types of suffix – inflectional and
derivational

Inflectional suffixes are grammatical: they show how
a word is being used in the sentence. They can show
number:
I
pick
 She picks

And they can also show tense
 I/We/She

picked
These suffixes change the grammar, but we can use
a derivational prefix to change the meaning of the
words – e.g., add un- to all the above.
How can we begin to analyze individual words?

Derivational suffixes are lexical, like prefixes.
They affect meaning by altering the word class.
Examples are:
darkness, headship, likeable.
They can be used to form verbs, abstract nouns,
concrete nouns, adverbs and adjectives.
Try to come up with at least one example of each;
or, can you think of common suffixes and
explain the change of class they bring about?

Can you explain the difference between these?

base, and label the effect of the prefix.
Give two inflections of the word ‘run.’
Give two examples of the other type of suffix.
