Distinguishing Between Adverbs and Adjectives

Sometimes the same word can be both an adjective and an adverb. To distinguish between them, it is important to look at the context of the word and its function in a sentence. 

For instance, in the sentence, "The fast train from London to Cardiff leaves at 3 o'clock," the word fast modifies and comes before a noun, train, and is, therefore, an attributive adjective.

However, in the sentence, "The sprinter took the bend fast," the word fast modifies the verb took and is, therefore, an adverb.

Interestingly, -ly is not the only suffix that can be added to the end of a word to change its meaning or be used by both adjectives and adverbs. Additionally, -er and -est can combine with adverbs in a much more limited way wherein the comparative form of an adverb is likely to add more or most to the beginning of the adverb phrase rather than adding an -er or -est.

It's important to refer to context clues when hints like the addition of an -ly or the word most to accompany a word doesn't tell you whether it is an adjective or adverb. Look to the word that is being emphasized. If the word being emphasized is a noun, you have an adjective; if the word being emphasized is a verb, you have an adverb.
