While both "accelerate" and "hasten" mean to make something happen faster, there's a subtle difference in their connotations. "Accelerate" typically implies a more significant increase in speed or rate, often in a measurable or technical way. "Hasten," on the other hand, suggests a more general speeding up, often with a sense of urgency or need to do something quickly. Think of it this way: accelerating a car involves precise mechanics, while hastening a task might involve rushing through it to avoid a deadline. Here are some examples:
