Understanding 'Course' vs 'Coarse'

This question asks us to identify the correct pair of words to complete the sentence: "Since you have gone off the ________, the ________ sand is likely to damage the car." We need to understand the difference between the words 'course' and 'coarse' to fill the blanks correctly.

Defining 'Course' and 'Coarse'

Let's look at the meanings of these commonly confused words:

• Course: This word has several meanings, but the most relevant ones here are:
  • A direction or path taken. Example: "The ship stayed on course."
  • A series of lessons or studies. Example: "She is taking a course in English."
• Coarse: This word primarily means:
  • Rough or having a rough texture. Example: "The sweater was made of coarse wool."
  • Lacking refinement; vulgar. Example: "He used coarse language."

Applying Words to the Sentence

Now, let's apply these definitions to the sentence blanks:

First Blank: "Since you have gone off the ________..."

• We are talking about driving or movement. Going "off the course" means deviating from the intended path or route.
• Going "off the coarse" doesn't make sense in this context.

Therefore, the first word must be course.

Second Blank: "...the ________ sand is likely to damage the car."

• Sand can be described by its texture. "Coarse sand" refers to sand with large grains, which would feel rough and could potentially scratch or damage a car.
• "Course sand" is not a standard description for sand in terms of its texture or type.

Therefore, the second word must be coarse.

Conclusion

Combining our findings, the sentence should read: "Since you have gone off the course, the coarse sand is likely to damage the car."

The pair of words that best fills the blanks is 'course, coarse'.
