Q1.
Add correct prefixes to the following words to create new words. Write the new word along with its meaning in the space given below. Prefix | Word | New word | Meaning Un- | common | uncommon | Something that is not easily found ___ | write | ___ | ___ ___ | aware | ___ | ___ ___ | comfortable | ___ | ___ ___ | arrange | ___ | ___ ___ | think | ___ | ___
Answer

First, the rule the book gives you. A prefix is a small part that we add at the front of a word. It changes what the word means.

  • un- means not.   un + happy = unhappy (not happy)
  • re- means again.   re + draw = redraw (draw again)

How to choose. Ask yourself one question: does the sentence mean not this thing, or does it mean doing this thing a second time? If it means not, use un-. If it means again, use re-.

Here is the completed table.

PrefixWordNew wordMeaning
Un-commonuncommonSomething that is not easily found. (This one was done for you.)
Re-writerewriteTo write something again, usually to make it better or neater.
Un-awareunawareNot knowing about something; having no idea that it is there.
Un-comfortableuncomfortableNot comfortable; not easy or pleasant to sit in, wear or be in.
Re-arrangerearrangeTo arrange things again, in a new order or a new place.
Re-thinkrethinkTo think about something again, and perhaps change your mind.

Now use each new word in a sentence:

  • A blue rose is uncommon, so people stop to look at it.
  • My handwriting was untidy, so I had to rewrite the whole page.
  • Ravi was unaware that the bell had rung.
  • The wooden bench was hard and uncomfortable.
  • We must rearrange the desks for the drawing class.
  • Our team lost, so the captain will rethink the plan.
Watch out: Not every word takes every prefix. We say unhappy, but never “rehappy”. We say rewrite, but never “unwrite”. Say the new word aloud — if it sounds wrong, it is wrong.
Why prefixes are useful: One small prefix saves you a whole sentence. Instead of saying “I will arrange the books again”, you can say “I will rearrange the books.” Three words become one.
