This paper is a survey of the possibilities of having the so-called Scandinavian or verb-third (V3) order in Icelandic embedded clauses, namely the order where the finite verb follows a sentential adverb (like the negation for instance). It is shown that although this order is possible in most types of embedded clauses in Icelandic, it is severely restricted and heavily marked. It commonly requires an extra stress on the adverb and it is frequently more acceptable if the subject is an unstressed pronoun. The naturalness of the order also depends on the type of embedded clause involved, being most natural in relative clauses and indirect questions introduced by a wh-pronoun but least acceptable in that-complements. It is argued that the proper analysis of this order in embedded clauses in Icelandic involves exceptional adjunction of the adverb in question to the TP instead of the usual VP-adjunction of such adverbs. Thus it is maintained that the Adv-V order in these clauses is not due to exceptional lack of V-movement in Icelandic but rather to exceptional AdvP-adjunction. In the Scandinavian languages, on the other hand, the V3 order in embedded clauses is argued to be best analyzed as lack of V-movement (lack of V-to-I), as usually assumed. The paper follows the analysis proposed by Bobaljik & Thra´insson (1998) in relating this difference between Icelandic and (Mainland) Scandinavian to the presence vs. absence of a split inflectional phrase. * I am indebted to Ho¨skuldur Thra´insson and Jo´hannes Gı´sli Jo´nsson for comprehensive comments on an earlier (Icelandic) version of this paper (Anganty´sson 2001) and to Christer Platzack and the two reviewers of Studia Linguistica, Halldo´r Á rmann Sigurðsson and an anonymous referee, for valuable comments on the English draft. I would also like to thank Molly Diesing, John Bowers and Masayuki Gibson for helpful comments and discussion, and Einar Freyr Sigurðsson for technical assistance. All remaining shortcomings are of course mine.The V3 order that I am presenting here is from three different sources. Firstly, I have made up my own examples, as a native speaker of Icelandic, on which the discussion is mostly built. Since the grammaticality is rather variable, in my view, the following detailed diacritics are used:(i) a. No diacritic = completely natural (although another word order might be more straightforward) b. ? = a little bit odd c. ?? = very strange d. ?* = bad but maybe not completely out e. * = ungrammatical Secondly, I have collected several examples from the Internet (via a Google search) and I list some of them in footnotes to show that this word order is not only in my idiolect. Finally, judgments of this word order were collected in connection with the Syntactic Variation Project in Iceland (see Thra´insson et al. 2005). The results from the pilot study confirm that the V3 phenomenon is very marked and needs specific prosodic adjustments to be accepted but there was no evidence for age-related, areal or social variation with respect to this word or...
