Identify Incorrect Adverbs in English Grammar

The question asks us to identify the incorrect adverb or adverbs from the given list of words. Let's examine each word:

• (a) fastly: The word "fast" functions as both an adjective (e.g., a fast car) and an adverb (e.g., runs fast). The form "fastly" is generally considered incorrect or non-standard English.
• (b) contemptuously: This word is formed from the adjective "contemptuous" by adding the suffix "-ly". It is a correct and commonly used adverb, meaning in a way that shows contempt.
• (c) slowly: This word is formed from the adjective "slow" by adding the suffix "-ly". It is a correct and commonly used adverb, meaning at a slow speed.
• (d) academically: This word is formed from the adjective "academic" by adding the suffix "-ally". It is a correct and commonly used adverb, meaning in a way relating to academics or scholarly matters.
• (e) seemly: The word "seemly" is primarily used as an adjective meaning proper or appropriate (e.g., seemly conduct). While it can occasionally be used as an adverb meaning "in a seemly manner," its use as an adverb is much less common and it is predominantly recognized as an adjective. In the context of standard adverbs, it might be considered 'incorrect' or at least less standard than the others ending in -ly.

Based on the analysis, "fastly" is widely considered incorrect as an adverb. "Seemly" is primarily an adjective, and its use as an adverb is rare compared to the standard adverbs in the list.

Therefore, the incorrect adverbs from the given list are (a) fastly and (e) seemly.
