Drawing on findings from an ethnographic study of the writing practices of three plurilingual writers in Toronto, Canada, this article focuses on the translingual practices that these writers engaged with and discusses how these practices enriched their writing processes and products both in English and in their mother tongues. The author explains how these writers' translanguaging was a complex process with five dimensions: (1) lexical, (2) syntactic, (3) rhetorical, (4) conceptual, and (5) presentational (how to present, share, and disseminate text). The article highlights how translanguaging contributed to the participants' larger semiotic engagements. Moving beyond the formulations of semiotic agility as a technical skill, the author explains how translanguaging helped the writers maintain their writing identities by creating semiotic and semantic continuity in their writing trajectories.
