choose the option opposite in meaning to the word or phrase in italics They come here on bootless errand

Analyze the question: We need the word opposite in meaning to "bootless" in the phrase "bootless errand."

Explain the concept: "Bootless" is an old-fashioned word. "Boot" here is not footwear. It comes from an old English word meaning "advantage" or "profit." So bootless means useless, unprofitable, without result, or in vain. A "bootless errand" is a trip or task that achieves nothing.

Step-by-step solution:

1. Meaning of "bootless": useless, fruitless, in vain.
2. We need the antonym, so we want a word meaning useful, profitable, or beneficial.
3. Check each option: • A. worthwhile: valuable, useful, rewarding. This is the opposite of bootless. ✔ • B. vain: fruitless. This is a synonym of bootless, so it is wrong. • C. delusive: misleading or deceptive. It is not an opposite. • D. intended: planned or deliberate. It has nothing to do with usefulness.

Answer: The opposite of "bootless" is worthwhile, which is option A.

Tip: In "opposite meaning" questions, first find the synonym of the word. Here, "vain" is a synonym and is placed among the options as a trap. When one option means the same as the word, eliminate it and look for the opposite. Also remember that "bootless" has nothing to do with shoes. "To boot" means "in addition, to advantage."
