Here’s another wordcloud with some extreme adjectives for this level. First look up the words in a dictionary. After, try to complete the crossword.
Extreme adjectives typically follow words like ‘absolutely’ or ‘extremely’ and either describe emotions or something that can cause a particular reaction, like ‘hilarious’. They are not gradable with words like ‘very’ because they already mean that whatever we are speaking about, has a certain feature, or provokes a certain reaction.
