What is dependency?The posthumous book by Tesni`re (1959) is considered a masterpiece, eas it introduces the two key concepts of dependency and valency.Nonetheless, unlike valency, there is no agreement among scholars andspecialists on how to treat precisely the concept of dependency. How Tesni`re really deﬁned dependency? e What can be saved – and adapted – from his work nowadays? 2 of 14

Tesni`re talked about connection, not dependency! e parle parle I ami I Alfred I mon Stemma 1 Stemma 2In Alfred parle (‘Alfred speaks’), the verb parle is the governor(r´gissant), the noun Alfred being the dependent (´l´ment e eesubordonn´). eTheir relation “indicated by nothing” (1, A, ch. 1, 4) is theirconnection (connexion). Connections are recursive (stemma 2). 3 of 14

Tesni`rian Structural Syntax triple eFor instance, in Alfred parle (Alfred speaks, stemma 1):1. governor (parle)2. dependent (Alfred)3. connector ( ) – empty? yes, but it does exist indeed!Tesni`rian unary trees – even if recursive – tend to obscure the econnector in the triple, especially when it is collocational (syntactic)instead than morphological. 4 of 14

Dependency in adpositional treesIn adpositional trees (adtrees): governors are put on the right, dependents on the left; adpositions are put in evidence; they deﬁne the structure of constructions through the adtree ﬁnal grammar character (F); left-to-right indicators (→) sign dependency, where the information prominence is in the dependent; right-to-left indicators (←) sign government, where the information prominence is in the governor; left-to-right & right-to-left indicators (↔) sign underspeciﬁcation, where the information prominence is not relevant. 6 of 14
