FAQ
Questions, answered
What is Coders Lingo and who is it for?
Coders Lingo (English for IT) is a free learning platform for software developers, QA engineers, DevOps specialists, and other IT professionals who want to improve their English in a technical context. Every exercise, glossary entry, and article is built around real workplace language — not general English.
Do I need to register or pay?
No registration and no payment required. All exercises, glossary pages, vocabulary, and blog articles are free. Your streak and XP are saved in your browser.
I'm a developer — where should I start?
Pick your role in Learning paths for a 30/60/90-day plan, or jump straight into Collocations and Code review — the two areas developers find most useful day to day.
What level of English do I need?
Content ranges from Beginner to Advanced and each exercise is tagged with a level. If you can read a README in English, you can start right away. No language test required.
How is this different from a general English course?
General courses teach you to book a hotel. Here every sentence comes from IT contexts: code reviews, Slack messages, standups, incident reports and pull requests — the vocabulary you will actually use tomorrow at work.
Does it help with job interviews in English?
Yes. The Interview Prep hub covers STAR answers, explaining technical concepts, system design phrases, salary negotiation and role-specific question sets.
Is the content UK or US English?
The primary focus is UK English, but IT vocabulary and collocations are universal. Where UK and US usage differ, both variants are noted.
