95–98%
The gap the glosses close
Research shows unassisted reading only feels comfortable when you know roughly 95–98% of a text's words — a bar authentic news sets impossibly high for almost every learner. LingoNews doesn't wait for your vocabulary to get there: the glosses supply the missing words in the moment. You don't need to understand everything — you need to keep reading, and understand enough to grow. That works at any level, and the habit does the rest.
