Words · tap a card to see it used
Grammar
In affirmative sentences, adding 'do', 'does', or 'did' before the base form of the main verb creates emphasis. This structure is used to insist, contrast, or express surprise. In present tense: 'I do believe', 'She does understand'. In past tense: 'They did manage'. Stress falls on do/does/did in speech.

Reading
When Priya launched her first tech start-up at twenty-three, she was convinced it would succeed. The idea was innovative, and the team did work incredibly hard throughout the first year. However, the company ran out of money within eighteen months. Critics said the product was ahead of its time, and they did have a point — the market was not ready. Priya could have abandoned entrepreneurship entirely, but she did learn a crucial lesson: timing matters as much as talent. She spent two years working in a large corporation, studying how established businesses scale. When she launched her second venture, she did things differently. She bootstrapped the company, iterated rapidly on customer feedback, and chose a scalable model from the outset. This time, the market was ready. Within three years, the company had over a million users. Priya does acknowledge that her first failure was painful, but she insists it was necessary. As she often tells aspiring founders: 'I do believe that every failure contains the blueprint for future success.'
1. Why did Priya's first start-up fail?
2. What did Priya do differently with her second venture?
