Adverbs: form and position

Adjective + -ly = adverb: quick → quickly, careful → carefully, easy → easily, terrible → terribly, basic → basically.

An adjective describes a noun; an adverb describes a verb, an adjective or another adverb: She's a careful driver. She drives carefully. It's really good.

After linking verbs (be, look, seem, feel, sound, taste, smell, become) use the adjective: You look tired. It sounds good. I feel bad.

Position:

• Frequency adverbs (always, usually, often, sometimes, never) go before the main verb but after be and after the first auxiliary: I often go there. She is always late. I have never seen it.
• Manner, place, time usually at the end, in this order: She sang beautifully (manner) at the concert (place) last night (time).
• Never between the verb and its object: I like coffee very much (not “I like very much coffee”). She speaks English well.
