Frequently Asked Questions
How do you form an adverb from an adjective?
Most adverbs add -ly to the adjective: quick → quickly, careful → carefully. Spelling rules: adjectives ending in -y change to -ily (happy → happily); -le drops e and adds y (simple → simply); -ic adds -ally (logic → logically); 'true' becomes 'truly'.
What is the difference between hard and hardly?
They are two different words. 'Hard' (the adverb of the adjective 'hard') means 'with effort': 'He works hard.' 'Hardly' means 'almost not': 'I can hardly hear you.' Similar pairs: late (after the time) vs lately (recently), and high (literal) vs highly (figurative, as in 'highly recommended').
Why is 'friendlily' wrong?
'Friendly' is already an adjective, not an adverb — even though it ends in -ly. The same is true of 'lovely', 'lonely', 'silly', 'ugly', 'costly'. To use them adverbially, paraphrase with 'in a ___ way': 'She smiled in a friendly way' (not 'friendlily').
Is it 'very enjoyed' or 'really enjoyed'?
Use 'really enjoyed' — 'very' does not modify verbs. Use 'really' or 'a lot' with verbs: 'I really enjoyed it' / 'She talks a lot'. Use 'very' before adjectives and adverbs: 'very interesting', 'very carefully'.
