For example, we often write sincere and best greetings at the end of emails, which is similar to our "greetings". But do you know what different ending words mean?
Let's arrange these concluding remarks in order from the most casual (intimate) to the most formal:
love
Very personal. Used between lovers, family members and close friends.
drink a toast
Very casual. For friends. If you want to look casual, you can use it among colleagues, but at the risk of sounding unprofessional.
be careful/cautious
Leisure, used between friends.
Thank you or thank you?
"Thank you" is very casual and "thank you" is very formal. Usually used in business situations. "Thank you" is a good way to send an email to a stranger, especially when you make a request or ask a question.
Yours or your heart or heart.
Leisure or business leisure. A more personal but still polite way to end. You may have met the recipient in real life.
Best or best wishes
Leisure or business leisure. A polite way of writing letters. Can be used between friends or strangers.
Sincerely or sincerely yours or yours sincerely.
Leisure, business leisure or formal. Standard letter tail. "Sincerely" is the most common ending, because it can be used to end both informal and formal responses. If you are not sure how to sign a letter, use "sincerely".
Greetings or sincere greetings.
Business, leisure or formal. If the recipient is someone you have never met in real life, you can use this.
cordially
Officially. Used in business letters when the subject of the letter is serious. Sometimes used when there is a conflict between the sender and the receiver.
Using an overly casual ending may not always be inappropriate. On the contrary, using a casual ending can show your confidence. But to do this, you need to judge whether the other person likes more casual conversation.
Cheers, more like a team. Everyone says "Come on"
Sincerity, used in more formal occasions, cliches, sincerity, letters of recommendation, resignation letters, other official documents, etc.
Greetings are roughly such salutations.
Best wishes/warm wishes, friendly and kind sympathy.
