The prefix im- in the word impractical gives a clue that this word means
A. Very useful
B. More useful
C. Not useful
D. Too useful
c. not usefull
To determine the meaning of the word "impractical," we need to analyze the prefix "im-" and its common usage. The prefix "im-" is a negative prefix, which means it changes the meaning of the word it is attached to. It is often used to indicate the opposite or absence of something.
In this case, the prefix "im-" suggests that the word "impractical" means "not practical" or "lacking practicality." This corresponds to option C, "Not useful."
To verify this, you can also consider the root word "practical," which means something that is useful, sensible, or capable of being carried out. By adding the negating prefix "im-," the meaning is reversed to indicate the absence of practicality.
Therefore, the answer to your question is C. Not useful.
