What it does
The Defense Language Institute's Global Language Online Support System provides searchable language lessons and grammar-note resources.
GLOSS is a free listening and reading resource chiefly described for intermediate and advanced learners. Filter by language, level, modality and topic to find a lesson that addresses a particular gap, then use its exercises and grammar notes. It is a supplement for developing comprehension rather than a beginner conversation course or a promise of a proficiency qualification. The separate DLI diagnostic tool can suggest GLOSS lessons from areas needing improvement.
