Fix the adjective error (if one exists).Gregory Goyle accepts only the most shiniestmost shiniestshiniest pennies on Earth into his coin collection.

The phrase "the most shiniest" contains an error in the use of the adjective "shiniest."

Breakdown of the Problem

1. Identify the adjective in the sentence.
2. Determine if the comparative or superlative form is correct.

Relevant Concepts

• "Shiny" is the base form of the adjective.
• "Shinier" is the comparative form.
• "Shiniest" is the superlative form.
• When using "most" with an adjective, it indicates the superlative degree, which means we shouldn't combine them.

Analysis and Detail

1. Most Shiniest: This construction is incorrect because "shiniest" already conveys the superlative meaning. "Most" should not be used with superlative adjectives like "shiniest."
2. Correct Usage: The sentence should either use "shiniest" by itself or the phrase "most shiny," which is less common but technically correct if "shiny" were being used in a comparative sense.

Verify and Summarize

The correct adjective usage here is "shiniest." Therefore, the appropriate correction is to change "the most shiniest" to simply "the shiniest."

Final Answer

Corrected sentence: "Gregory Goyle accepts only the shiniest pennies on Earth into his coin collection."
