Open Educational Resource (OER): A 100% SFW Internet English & Slang Dataset + Lesson Plan for ESL Classrooms

AI disclosure: educational resource guide prepared from SlangLane’s source-checked general-audience dictionary entries. Editorial methodology.

Language learners and NLP educators frequently ask for a clean, classroom-safe (100% SFW) reference for modern internet English (lowkey, cooked, delulu, touch grass, ate, rent-free) and British/Irish conversational slang (craic, grand, sound, knackered, gutted, skint) that excludes explicit adult vocabulary.

We published a dedicated Classroom & ESL Teacher Kit under Creative Commons Attribution 4.0 (CC BY 4.0) at slanglane.com/esl.

What Is Included

1. Strict SFW Filter: Every entry on /esl and in /api/dataset.csv?mature=false is filtered to maturity = general.
2. 45-Minute B1–C2 Lesson Plan: Focuses on register — helping second-language speakers distinguish between group-chat irony, casual spoken English, and formal workplace writing.
3. Printable Matching Worksheet + Teacher Answer Key: Automatically generated from the current verified release.
4. Anki, Quizlet & Spreadsheet Exports: Direct UTF-8 CSV (/api/dataset.csv?mature=false) and JSONL (/api/dataset.jsonl?mature=false) endpoints.
