247. Adverbs and the accusative case.—Adverbs exercise no influence on case (see par. [243]), but used adverbially, participles of active verbs are followed by the accusative if used without a preposition (see par. [66] (b)).
After such adverbs as konforme, rilate, escepte, spite, etc., it is optional either to use the accusative or to add a suitable preposition with the complement in the nominative, as konforme al, kun, or je; rilate al; escepte de (or, kun la escepto de = with the exception of); spite de (see par. [258] (a)).
248. Comparatives and superlatives.—These are marked in the same way as adjectives (see pars. [112]–114).
Examples.—Pli rapide, ol bone = More quickly than well. Malpli forte, ol kutime = Weaker (less strong) than customary. Tiel dolĉe, kiel eble (or, kiel eble plej dolĉe) = As sweetly as possible. Ŝi kantas la plej bone el ĉiuj = She sings best of all. Li agis tre saĝe = He acted very wisely.
