Adverbs modify meaning when they’re added to a sentence. Use them occasionally to show people how, when, where, or the extent to which something happens.
Adverbs add more information about other types of words
Adverbs modify verbs, adjectives and other adverbs. They often, but not always, end in ‘-ly’.
- The staff worked happily. [Modifies the verb ‘worked’]
- The staff arrived early this morning. [Modifies the verb ‘arrived’]
- She is a very dedicated worker. [Modifies the adjective ‘dedicated’]
- You finished quite quickly. [Modifies the adverb ‘quickly’]
Adverbs can affect clarity
Use adverbs sparingly. Remove any adverb that doesn’t play a critical function in a sentence.
Because adverbs are modifiers, they can affect clarity. A lack of clarity can cause users to lose trust in government content.
Comparison with adverbs is by degree
Like adjectives, adverbs can have degree to show or imply a comparison. In general, you simply add the word ‘more’ or ‘most’ in front of the adverb.
Depending on the context, some words can be adjectives or adverbs. Make sure you use the correct form. For example, ‘quickest’ is the adjective and ‘most quickly’ is the adverb.
Bob spoke more quickly than Tom. [Uses ‘more’ to compare Tom’s and Bob’s speaking speed]
Tom speaks more quickly than Bob, but Harry speaks the most quickly of them all. [Uses ‘most’ to compare Harry’s speaking speed to that of the others]
Not all adverbs follow this regular pattern of using ‘more’ or ‘most’ to show comparison. The following examples show irregular adverbs.
- He spoke well, but she spoke better.
- You finished work early, but they finished even earlier.
Adverbs don’t always show or imply comparison. These are called positive adverbs.
- Tom spoke quickly. [Tom’s speaking speed is not compared with anything else.]
- The staff worked happily. [We don’t know if they worked more happily than others.]
