Modifying comparatives and superlatives (adverbs)
You use modifiers such as a bit, a little, a little bit, slightly, much, a lot in comparisons to show the degree of difference between the two things being compared: small difference: this holiday is a bit cheaper; it works slightly better big difference: you can book much more cheaply online With plural countable nouns, for small differences use a few more or slightly more. Say a few more hours (don’t say a-bit or a little more hours).
With plural countable nouns, for big differences use many more or a lot more. Say many more hours (don’t say much more hours).
even We can use even to add emphasis to a comparative expression: even less fun even more cheaply than before even fewer people than we’d expected
We use the same forms for adjectives, adverbs and uncountable nouns: Small differencesbig differences a bitcheapermuchcheaper a littlemorea lotmore slightlycarefullyfarcarefully more time considerably more time
Modifying superlative expressions We can use modifiers such as easily and by far with superlative expressions to say that something has much more of a particular quality than all the other things it is being compared to: easily: this is easily the most exciting (= much more exciting than anything else) This is easily the most time we've spent away from home. by far: this is by far the best (= much better than anything else) This is by far the most interesting place we’ve visited during this holiday.
