Je vous remercie, ainsi que je vous souhaite d'avoir un jour béni
Thank you for the well wishes! I'm preparing diligently and feeling confident about my French oral exam tomorrow. Wish me luck!
to wish = souhaiter, désirera wish = un souhait (masc.)
You need to state the language you wish to say it in.
Simply saying 'thank you' or '(I, we) wish to express our thanks' (for your time, help, services, and so on) is perfectly acceptable and correct in formal and informal circumstances. You might qualify or amplify it by saying, 'My associates and I (wish to thank you)', or 'The partnership wishes to express its thanks...', or 'Please accept our thanks for...', or 'We wish to thank you most sincerely for...' and so on.
In French, you can say "bonne chance et sois bien" to wish someone good luck and well-being.
The translation of "I wish I spoke French" in French is "J'aimerais parler français".
Thank you
Who can responds for birthday wishes
To wish a good departure or say goodbye in French you would say au revoir.
When someone gives you a birthday wish, it is fine to give a simple thank you as a reply.
Thank the boss for all he/she has done for the company/department/section and remember to wish him/her all the very best for the future.
You can simply say Thank you to the other person. You could also say Bless You to them.
