Analyzing the Sentence for Grammatical Errors

The sentence provided is "The project was completed / more quicker / than expected." We need to examine each part to identify any grammatical error.

Examining Each Part of the Sentence

• Part 1: "The project was completed"

  This part uses the passive voice ("was completed"), which is grammatically correct in this context. It indicates that the project was the recipient of the action of completion.

• Part 2: "more quicker"

  This part contains an error. "Quicker" is already the comparative form of the adjective/adverb "quick". Adding "more" before "quicker" creates a double comparative, which is redundant and grammatically incorrect. The correct comparative form should be either "quicker" or, using the adverbial form "quickly", it would be "more quickly". Since the word modifies the verb "completed" (describing how it was done), an adverbial form is appropriate. Both "quicker" (functioning as an adverb here) and "more quickly" are correct alternatives.

• Part 3: "than expected"

  This is a standard comparative phrase, correctly used here to complete the comparison introduced by the comparative form. It is grammatically sound.

Identifying the Error Location

Based on the analysis, the error lies in the phrase "more quicker" due to the incorrect use of a double comparative.

Correcting the Error

The sentence could be corrected in two ways:

• "The project was completed quicker than expected."
• "The project was completed more quickly than expected."

Both corrected sentences are grammatically sound.

Conclusion on the Grammatical Error

The part of the sentence containing the grammatical error is "more quicker". This is because "quicker" is already a comparative form, and adding "more" before it creates an incorrect double comparative.

Additional Information: Double Comparatives Explained

A double comparative occurs when you use both "more" (or "less") and the "-er" ending to form the comparative degree of an adjective or adverb. This is considered incorrect in standard English grammar. Examples of incorrect double comparatives include:

• More quicker (should be quicker or more quickly)
• More happier (should be happier)
• More colder (should be colder)

Generally, one-syllable adjectives/adverbs and some two-syllable ones form their comparative with "-er", while most two-syllable adjectives/adverbs and all three-or-more-syllable ones use "more".

In the case of "quick", it can function as both an adjective and an adverb. Its comparative is "quicker". "Quickly" is the adverbial form, and its comparative is "more quickly". Both "quicker" and "more quickly" can function as adverbs modifying verbs like "completed", but "more quicker" is never correct.
