be formed with the basic form instead of the t-form, especially those ending in -ig, -lig and -vis: det forstår han selvfølgelig ikke, "that, of course, he does not understand"; the t-less form of such adverbs is obligatory when the adverb is isolated (i.e. with no corresponding adjective) or the meaning of the adverb is essentially different from that of the adjective (e.g. endelig, "finally, at last" ~ endeligt, "definitively"). In other cases, the t-less form is preferred when the adverb qualifies an adjective (e.g. væsentlig(t) større, considerably larger"). The comparative and superlative of some frequent adjectives have umlaut: e.g. lang, længere, længst, "long, longer, longest"; ung, yngre, yngst, "young, younger, youngest"; stor, større, størst, "big, bigger, biggest". One adjective is suppletive: lille, "little, small" (n- and t-form and definite e-form) ~ små (plural e-form), småt (adverb t-form). Six adjectives are suppletive in the three degrees of comparison: god, bedre, bedst, "good, better, best"; dårlig, værre, værst, "bad, worse, worst"; gammel, ældre, ældst, "old, older, oldest", mange, flere, flest; "many, more, most"; megen/-et, mere, mest, "much, more, most"; lille / lidt, mindre, mindst "little, less / smaller, least / smallest". Irregular, but not suppletive are få, færre, færrest, "few, fewer, fewest" and nær, nærmere, nærmest, "close, closer, closest". Interjections Danish has a number of interjections. Emotive interjections include 'ow' among others. Response tokens include and 'yes' and 'no', and (approx. 'oh'), and . When responding to polar questions, and are sensitive to the presence of a negation ( 'not', 'nobody' or 'never') in the question, so that confirms a negated statement, and , an alternate form of is used to disconfirm a negated statement. They can be used in various combinations with other words (including other response tokens). Syntax Danish is a V2-language, meaning that the finite verb can usually be found in second position in a main clause. The basic sentence structure is Subject-Verb-Object. Paul Diderichsen developed a model of the Danish sentences with different slots to be filled. Main Clauses According to Diderichsen's model, main clauses have the following structure: Not every slot of the model needs to be filled in order to form a grammatical main clause. The model shows relative positions of constituents, especially in relation to the finite verb. So a sentence like is fully grammatical even though not every slot of the clause model is filled. The only position that is obligatory to form
