more words that serve different functions. However, this distinction can be useful, especially when considering adverbs like naturally that have different meanings in their different functions. Rodney Huddleston distinguishes between a word and a lexicogrammatical-word. Grammarians find difficulty categorizing negating words, such as the English not. Although traditionally listed as an adverb, this word does not behave grammatically like any other, and it probably should be placed in a class of its own. In languages In Dutch adverbs have the basic form of their corresponding adjectives and are not inflected (though they sometimes can be compared). In German the term Adverb is defined differently from its use in the English language. German adverbs form a group of uninflectable words (though a few can be compared). An English adverb which is derived from an adjective is arranged in German under the adjectives with adverbial use in the sentence. The others are also called adverbs in the German language. In Scandinavian languages, adverbs are typically derived from adjectives by adding the suffix '-t', which makes it identical to the adjective's neuter form. Scandinavian adjectives, like English ones, are inflected in terms of comparison by adding '-ere'/'-are' (comparative) or '-est'/'-ast' (superlative). In inflected forms of adjectives, the '-t' is absent. Periphrastic comparison is also possible. In most Romance languages, many adverbs are formed from adjectives (often the feminine form) by adding '-mente' (Portuguese, Spanish, Galician, Italian) or '-ment' (French, Catalan) (from Latin mens, mentis: mind, intelligence, or suffix -mentum, result or way of action), while other adverbs are single forms which are invariable. In Romanian, almost all adverbs are simply the masculine singular form of the corresponding adjective, one notable exception being bine ("well") / bun ("good"). However, there are some Romanian adverbs built from certain masculine singular nouns using the suffix "-ește", such as the following ones: băieț-ește (boyishly), tiner-ește (youthfully), bărbăt-ește (manly), frăț-ește (brotherly), etc. Interlingua also forms adverbs by adding '-mente' to the adjective. If an adjective ends in c, the adverbial ending is '-amente'. A few short, invariable adverbs, such as ben ("well"), and mal ("badly"), are available and widely used. In Esperanto, adverbs are not formed from adjectives but are made by adding '-e' directly to the word root. Thus, from bon are derived bone, "well", and bona, "good". See also: special Esperanto adverbs. In Hungarian adverbs are formed from adjectives of any degree through the suffixes -ul/ül
