1. It is the year 2019.
2. It is 2019.
[Are both okay?]
3. I have to urinate.
4. I need to defecate.
[Are these expressions formal and polite expressions?]
1 and 2 -- Yes, both are fine.
3 and 4 -- These are technically correct statements, but not to be used in public or even some private groups. Usually, people say one of these in formal situations:
I need to use the men's room.
I need to go to the ladies' rest room.
im feeling akward... meow meow
1. Both "It is the year 2019" and "It is 2019" are correct and acceptable ways to express the current year. They convey the same information and can be used interchangeably.
2. The expressions "I have to urinate" and "I need to defecate" are technically correct and straightforward ways to express the need to use the restroom. However, they are considered direct and quite informal. In formal or polite contexts, it is more appropriate to use less explicit phrases such as "I need to use the bathroom" or "I need to go to the restroom." These expressions maintain politeness while still conveying the same intention.
