Writers also sometimes overuse accelerate in formal content. Repeating it several times can make the writing feel mechanical. Alternatives such as expedite, hasten, boost, advance, stimulate, propel, and speed up can improve variety.
Avoid using a synonym without checking its exact meaning. Expedite works well for a process but may sound unnatural for a moving car. Quicken suits pace or movement but may not be the best choice for economic growth.
Be careful with vague wording. Instead of saying that a change accelerated something, explain whether it accelerated growth, production, learning, approval, development, or completion.
Finally, choose natural phrasing for the audience. Speed up often sounds better in casual conversation, while accelerate and expedite are often more suitable in formal reports.
Conclusion
Synonyms for accelerate include speed up, hasten, quicken, expedite, advance, boost, propel, stimulate, intensify, and increase the pace. The best choice depends on what is becoming faster. Use expedite for formal processes, quicken for movement or pace, boost for growth and performance, propel for strong forward progress, and hasten when something happens sooner.
