A Simplified Grammar of the Swedish Language/Part I/Adverbs
Many Swedish adverbs are identical with the neuter of the corresponding adjective, as tungt, 'heavily,' from tung, m., f., tungt, n., 'heavy.' In such cases they follow the same rules of comparison as the corresponding adjective; as, tyngre, 'more heavily;' tyngst, 'most heavily.' Many adverbs of irregular modes of comparison are similarly identical with the corresponding adjectives; as—
väl, well, comp. bättre, better, superl. bäst, best. illa, badly, " värre, worse, " värst, worst.
The following are some of the more generally used adverbs of time, place, manner, mode, affirmation, negation, etc.—
nu, now. här, here. gerna, willingly. då, then. dit, thither. visst, certainly. snart, soon. hit, hither. ja, jo, yes. strax, immediately. in, inne, in. nej, ej, no, not. redan, already. ut, ute, out. icke, no, not. länge, long. framdeles, in future. ingalunda, by no means. ofta, often. huru, how. hvarför, why. månne, may be perchance. der, there. så, so.
