Choose the option opposite in meaning to the word or phrase in italics:
They come here on bootless errand.
Answer Details
The option opposite in meaning to "bootless" is "worthwhile".
"Bootless" means unsuccessful, pointless, or unproductive, so if someone is on a "bootless errand", it means they are doing something that is unlikely to succeed or achieve their intended goal.
On the other hand, "worthwhile" means something that is worth the time, effort, or money invested in it. If someone is on a "worthwhile errand", it means they are doing something that has a good chance of succeeding and achieving their goal.
Therefore, "worthwhile" is the opposite of "bootless".
