Answer question 18 --by Yvonne

18. Sometimes we use '-est', but sometimes we just add a 'most' in front of the superlative adjective. And for the word 'fast', we use 'the fastest' to represent the superlative adjective, while the word 'beautiful' is represented by 'the most beautiful'. I would like to know when to use '-est' or 'most'.


when the word is short, we use ''est'',  and when word is too long to put an extra ''est'' , we use ''most'' .
