Hello fellas, how was your day?
In this session we will discuss derivative which is a part of grammar in English language. There are several grammatical rules to apply when using English. Today, we will continue with ‘Derivatives.’
Derivatives are word that are derived from other words, which we call root words. Usually, derivatives are formed by adding an affix to the root words.
Let’s see the paragraph below:
At their first session, the lawyer asked Ed, “What things about this woman that attracted you?”
Ed replied, “Her forthrightness, straightforwardness, and frankness.”
Fellas, did you find any derivatives from that paragraph?
From that paragraph, the words ‘forthrightness,’ ‘straightforwardness,’ and ‘frankness’ are derivatives. Derivatives can also be nouns that we could change into adjectives or adverbs if we add suffix at the end of the words. However, there are some derivatives that still retain their meaning.
1. To form noun derivatives, we add suffixes like -ness, -ty, -hood, -ian, -cy, -er, -or, -sion, -ment, -tion, -ant, -ce, etc.
Happy – Happiness
Child – Childhood
Dense – Density
Pregnant – Pregnancy
Good – Goodness
Comedy – Comedian
Assist – Assistance
Friend – Friendship
2. To form adjective derivatives, we add suffixes like: -full, -less, -ish, -al, – cy, – ary, -able, -ous, -y, etc.
Blue – blueish
Boy – boyish
Help – helpless
Sun – sunny
Danger – dangerous
3. To form verb derivatives, we can add affixes like dis-, re-, -ize, a-, -fy.
Like – dislike
Agree – disagree
Check – recheck
Memory – memorize
Summary – summarize
4. Derivatives can also form ‘negative words’ or words that have the negative meaning of the root words. To form these derivatives, we add prefixes un-, in-, im-, etc.
complete – incomplete
happy – unhappy
direct – indirect
mortal – immortal
