Cách dùng "Very", "Really" và "Absolutely" trong tiếng Anh.

Adverbs
Very, really, and absolutely are adverbs. They modify adjectives and other adverbs. They are usually placed before the adjective or adverb that they are modifying.

Gradable adjectives
Gradable adjectives are describing words that can be modified to make their meaning more or less intense. Words such as: a little, quite, really, and very are able to modify this group of adjectives. Examples of gradable adjectives are: happy, good, hot, funny.
EX:
– I’m very happy.
– The weather’s been really hot lately.
– The film wasn’t good. It was only a little funny.

Non-gradable adjectives
Non-gradable adjectives (also known as extreme or strong adjectives) cannot be used with words such as very. This is because they already contain the idea of very. The word thrilled means very happy. Because of this, when we wish to make a non-gradable adjective stronger, we need to use words such as ‘really’, ‘utterly’ or ‘absolutely’. Finally, many gradable adjectives have non-gradable pairs: very happy – thrilled, very good – wonderful, very hot – boiling, very funny – hilarious.
EX:
– I’m absolutely thrilled!
– The weather’s been boiling lately.
– The film was absolutely wonderful. The dialogue was utterly hilarious!
