Ser vs. Estar: The Advanced Cases
You learned the beginner rule years ago, but location versus events, passive versus resultant state, and adjectives that change meaning still cost B2 learners marks on the DELE.
10 Netflix Shows for Intermediate Spanish
Netflix shows for B1–B2 Spanish learners, sorted by dialect and real difficulty, so watching stops being passive and starts building the language you'll actually speak.
Por vs. Para: A Decision Guide
Para points toward goals and destinations; por explains causes, routes, duration, and exchange, with one decision test for each choice.
Geoff Bloom
Language Learner and Dioma Founder
I built Dioma’s approach to answer a question that I kept hitting on my language learning journey: “What actually moves the needle at the intermediate plateau, and what doesn’t?”
After 10 years of language learning across Spanish and Hebrew, I did a 6 month experiment where I tracked my errors by hand for a year.
Because of my busy life (3 kids, career)- the part of my routine that required feedback, speaking and writing, only made up eight to ten percent of my time.
I decided to build Dioma to close that gap, with targeted practice and real-time corrections on what you produce.
