Not as hot as yesterday

Although it is quite possible to say “it’s less hot” or “it’s less interesting” English speakers generally avoid this construction. Here are a few examples that you can use as reminders:

New York is bigger than London – … plus grande que…

Philosophy is more interesting than physics – … plus intéressante que …

London is as big as Paris – …aussi grande que…

physics isn’t as interesting as philosophy –moins intéressante que

It’s not as hot as yesterday – il fait moins chaud qu’hier
