What it is
Explainer is a free grammar reference for English language teachers. It lists every grammar concept on Lingadoo, grouped by category and CEFR level, and each entry opens a page with the concept explained and examples of it in use.
Search for a structure or browse the categories, then select a concept to jump straight to its explanation, examples and linked resources. Use it to check a form before a lesson, or to put an explanation on the classroom screen when a question comes up mid-class.
