A formal way to thank someone deeply for something they did.
“I would like to extend my sincere gratitude for your support during my training.”
“I would like to extend my sincere gratitude to the entire team for their hard work.”
Use this phrase in CELPIP Writing Task 1 emails that thank someone formally, such as a manager, teacher, or organization, rather than a close friend. It sounds more elevated than a simple 'thank you,' which can help fulfill tasks that specifically ask you to show appreciation.
Synonyms: I sincerely thank you, I am deeply grateful, please accept my heartfelt thanks
