The continued emergence of content and language integrated learning (CLIL) is linked to how it creates, adopts, and leads to the design of innovative didactic processes. In systems, theory emergence occurs when features of smaller entities are brought together through interaction to form a larger ecosystem, one that acquires qualities not readily accessible to the original sources. Having drawn on the theoretical underpinning of a range of language and broader educational philosophy, the emergence of CLIL is driven by processes and practices. This article conceptualizes subsystems of CLIL and describes how CLIL practice through English can be designed and implemented through phenomenon-based learning. CLIL practice provides a systemic process by which to simultaneously advance not only additional language fluency but also adoption of innovative methods across the curriculum.
