(Hemos desayunado más temprano de lo normal.)
Adverbs early, late, soon and fast make the comparative and superlative with –er and –est, e.g.:
| We had breakfast earlier than usual. (Hemos desayunado más temprano de lo normal.) |
| They arrived later than me. (Llegaron más tarde que yo.) |
| The rain stopped sooner than we expected. (Paró de llover antes de lo que se esperaba.) |
| Sue can swim much faster than I can. (Sue puede nadar mucho más rápido que yo.) |

Other adverbs use more and most, e.g.:
| He's behaving more sensibly these days. (Últimamente se comporta de manera más sensata.) |
Note that the superlative of adverbs is infrequent.
