This paper reports a study of the forms and functions of head movements produced in the dimension of depth in Finnish Sign Language (FinSL). Specifically, the paper describes and analyzes the phonetic forms and prosodic, grammatical, communicative, and textual functions of nods, head thrusts, nodding, and head pulls occurring in FinSL data consisting of a continuous dialogue recorded with motion capture technology. The analysis yields a novel classification of the kinematic characteristics and functional properties of the four types of head movement. However, it also reveals that there is no perfect correspondence between form and function in the head movements investigated.

This paper investigates the interplay of constructed action and the clause in Finnish Sign Language (FinSL). Constructed action is a form of gestural enactment in which the signers use their hands, face and other parts of the body to represent the actions, thoughts or feelings of someone they are referring to in the discourse. With the help of frequencies calculated from corpus data, this article shows firstly that when FinSL signers are narrating a story, there are differences in how they use constructed action. Then the paper argues that there are differences also in the prototypical structure, linkage type and non-manual activity of clauses, depending on the presence or non-presence of constructed action. Finally, taking the view that gesturality is an integral part of language, the paper discusses the nature of syntax in sign languages and proposes a conceptualization in which syntax is seen as a set of norms distributed on a continuum between a categorial-conventional end and a gradient-unconventional end.

This paper deals with the coordination of clauses in Finnish Sign Language (FinSL).Building on conversational data, the paper first shows that linking in conjunctive coordination in FinSL is primarily asyndetic, whereas in adversative and disjunctive coordination FinSL prefers syndetic linking. Secondly, the paper investigates the nonmanual prosody of coordination: nonmanual activity is shown both to mark the juncture of the coordinand clauses and to draw their contours. Finally, the paper addresses certain forms of clausal coordination in FinSL that are sign languagespecific. It is suggested that the sign language-specific properties of coordination are caused both by the fact that signers can use two manual articulators in the production of sentences, and by the pervasive iconicity of sign language structure.

This paper deals with syntactic ellipsis in clauses in Finnish Sign Language (FinSL). The point of departure for the paper is the observation, confirmed by several studies, that clauses in FinSL are often syntactically incomplete. Building on this, the paper first describes how all core-internal clausal material may be elided in FinSL: core arguments in clauses with a verbal nucleus, core-internal NPs in clauses with a nominal nucleus, and even nuclei themselves. The paper then discusses several grammatical contexts which especially favor ellipsis in FinSL. These are question–answer pairs, two-clause coordinated structures, topic–comment structures, blend structures, and structures containing gesturally indicating Type 2 verbals. Finally, the paper argues that FinSL conforms to the main characteristics of a discourse-oriented language, and that FinSL clauses are not highly governed units syntactically.

It is argued in this paper that equative sentences in Finnish Sign Language (FinSL) conform to the general schema of (NP) NP+(PI+)NP, parenthesis marking optionality of elements. With respect to this schema, it is further argued, (a) that the function of the first NP in equative sentences is always topic; (b) that topics are marked syntactically, prosodically, and morphologically in FinSL; (c) that the preferred organisation of equative sentences in general is topic-comment; (d) that there are two structurally distinct topic-comment structures in FinSL, one having the topic at the beginning of the clause and the other having the topic in the left-detached clause-external position; (e) that the double-indexing phenomenon (cf. pronoun copy) is functionally a means to increase textual cohesion; and (f) that the sign PI in equative sentences is a certainty expressing modal device, although it may be in the process of grammaticalising into a copula.
