There are 9 parts of speech or word classes in English language:
– nouns
– pronouns
– determiners
– verbs
– prepositions
– adjectives
– adverbs
– conjunctions

We use adverbs to explain or describe:
– verbs,

How to Form Adverbs of Manners

We can form adverbs of manner by adding -ly at the end of adjectives.

quick (adjective)
-> quickly (adverb)

careful (adjective)
-> carefully (adverb)

beautiful (adjective)
-> beautifully (adverb)

(1) Most adjectives:

adjective + -ly

correct -> correctly
wrong -> wrongly
slow -> slowly

(2) Adjectives ending with -able/-ible:

change -e to -y

comfortable-> comfortably
sensible -> sensibly

change -y to -ily

happy-> happily
angry -> angrily

(4) Adjectives ending with -ic:

change -ic to -ically

heroic-> heroically
energetic -> energetically
scientific -> scientifically

(5) Not all words ending with -ly are adverbs.
friendly (adjective)
lovely (adjective)
lonely (adjective)

(6) There are adverbs that do not end with -ly.
fast (adjective)
-> fast (adverb)
That car is fast. (fast = adjective)
