When to Add “ly” at the End of a Word
Do you wonder when to add -ly to a word? For example, should you say, “He speaks slow” or “He speaks slowly”? What about, “He speaks slower than his brother”? Is this correct? Let’s find out.
Adjectives describe nouns and pronouns. They may come before the word they describe: “That is a cute puppy.” Adjectives may also follow the word they describe: “That puppy is cute.”
Adverbs modify adjectives, verbs, and other adverbs. If an adverb answers how and can have an -ly attached to it, place it there.
Example: She thinks slow/slowly. Slowly answers how she thinks.
Example: We performed bad/badly. Badly answers how we performed.
Example: She thinks fast/fastly. Even though fast answers how she thinks, there is no such word as fastly.
When comparing, don’t drop the —ly. Simply add more or less in front of the adverb.
Example: Answer the questions more quickly/quicker to win the prize.
English grammar has one tricky caveat that seems like an exception to these easy rules: If the verb is one of these four senses–taste, smell, look, feel–don’t ask how. Instead, ask if the sense verb is used actively. If so, attach the -ly. If the sense verb is not used actively, which is more common, don’t attach -ly.
Example: Roses smell sweet/sweetly. Do roses actively smell with noses? No, so no -ly.
Example: The woman looked angry/angrily. Is the woman actively looking with eyes? No, only her appearance is being described.
Example: She feels bad/badly about the news. She is not feeling with fingers so no -ly.
Example: She feels bad/badly since burning her fingers.
In this sentence, she is feeling with fingers so the word is being used actively; therefore, add the -ly.
1. I feel bad/badly about telling that secret.
2. Walk slower/more slowly, please.
3. You look sad/sadly about the news.
2. more slowly
