English is full of phrasal verbs. Native speakers use them constantly — in conversation, in texts, in emails, in literature. But learners quickly discover a frustrating truth: the same phrasal verb can be perfectly natural in one context and completely wrong in another. Break down works beautifully in everyday speech. In a legal document, you need dissolve. In an academic paper, disintegrate. Knowing the difference is what separates a competent speaker from a truly fluent one.

For every phrasal verb in our library, we map out its equivalents across four registers — informal, professional, academic, and formal — and show you exactly how to use each one correctly. We highlight the most common mistakes learners make in each context, and we back everything up with real examples, audio, and authentic texts.

SwapVerbs is one platform inside a connected ecosystem designed for serious English learners. WeeklyCross teaches phrasal verbs through rich historical and cultural narratives. Flowglish builds fluency through structured practice by grammar complexity level. FlipVerbs explores opposite phrasal verb pairs. Together, they form a coherent learning environment where every encounter with a phrasal verb is meaningful, contextualised, and memorable.

SwapVerbs was created by Alessandra Fernandes Nóbrega, a Brazilian educator with 37 years of teaching experience and an M.A. in History of Education from UFPB. Alessandra built this ecosystem from scratch — starting with no web development experience — because she believed that language learning deserved better than isolated drills and decontextualised word lists. Her approach is rooted in CLIL methodology: teaching language through content that is genuinely interesting and worth thinking about.
