Questions & Answers about यह प्लान असफल रहा।
यह means this here, referring to this plan.
In modern speech, it is often pronounced roughly like yeh. In very careful reading, you may also hear something closer to yah, but yeh is what learners will commonly hear in everyday Hindi.
प्लान is a borrowed word from English plan, written in Devanagari. This is very common in modern Hindi, especially in casual speech, business, media, and everyday conversation.
A more traditionally Hindi/Sanskrit-based alternative would be योजना.
So these are both possible:
- यह प्लान असफल रहा।
- यह योजना असफल रही।
The second one sounds more formal or more purely Hindi.
