FORMAL GREETINGS
Good morning !
Good afternoon !
Good evening !
These greeting examples are used to salute people depending on the time of day. Good morning is typically used to greet people from dawn to noon, while good afternoon applies from noon to dusk or 6:00 p.m. You can use good evening after sunset. While professionals may use these greetings for business communications, they're also suitable for informal situations.
People use them to greet customers, colleagues, neighbours, family members and pedestrians they meet on the road. If you enter an office, hotel or restaurant, the variation of this greeting suitable for the time of day is most likely what people at the establishment are going to use to welcome you. You can also use it as a salutation in letters, followed by sir/madam, especially if you don't know the recipient's name.
INFORMAL GREETINGS
Informal greetings are ideal for situations where the atmosphere is cordial. You can use it when you're having a casual meeting with colleagues, such as during a coffee break or networking event. These salutations are also ideal for greeting friends, family and neighbours or even meeting with your team in the office. Here are four examples of informal greetings:
Hello !
Hi !
Hey !
What’s up
Hello, hi and hey are the most common informal greetings. You can use them to greet someone you may or may not know outside of the office. Hello is ideal for getting someone's attention, especially if you're not physically close to them. It's also appropriate for greeting someone over the phone. These salutations are also suitable for starting business conversations, such as emails, if you have a relationship with the recipient. Hey is most appropriate for greeting people you already know, although you can also use it for strangers if you pronounce it lightly.
