Two concepts of multilingualism that relate to the selves aspect of Dörnyei's (2009) L2 motivational self system (L2MSS) are highlighted in this article: Thompson's concept of "perceived positive language interaction" (PPLI) and Henry's notion of the "ideal multilingual self." With the dynamic model of multilingualism informing both concepts (Herdina & Jessner, 2002; Jessner, 2006, 2008), the intangible advantage that multilingual speakers have over monolingual speakers is clearly articulated in the discussion of this topic. The interconnectivity of language systems is an inherent aspect of the DMM; as such, both Thompson with PPLI and Henry with the ideal multilingual self incorporate the DMM as a framework to indicate the fluid nature of these constructs as additional language learning experiences are added to the system over time. This article further explores the dynamicity of multilingual learners' language systems and the influences that induce change. Specifically, data from Thompson's (2017b) study on LOTE learners are reexamined to explore this question. Additionally, excerpts from Natasha Lvovich's (1997) "The Multilingual Self," an autobiography of an L1 Russian speaker, are analyzed to present different possible models of incorporating the multilingual self and PPLI. The article ends with a discussion of an inherently multilingual context, as well as thoughts regarding the possibility of different types of future selves.
