1. A justice/judge of the Supreme Court is appointed by the president with the approval of the National Assembly.

(Can we use both judge and justice? Which one is commonly used?)

2. Both were fired after the incident/case.

(Can we use both judge and justice? Which one is commonly used?)

3. The new design will eventually replace all existing models.

4. The new design will eventually take place of all existing models.

5. The new design will eventually take the place of all existing models.
(Are the three all grammatical? What other expressions can we use instead of 'replace'?)

1. Both are used, but at Supreme Court level, they are usually referred to as Justices.

2. ???

3. OK

4. no

5. OK

I can't think of anything else to replace "replace" that would mean the same thing!

Thank you for your help.....

2. Both were fired after the incident/case.

(Can we use both incident and case? Which one is commonly used?) <== corrected...

I'd use only "incident," not "case."

1. Yes, both "judge" and "justice" can be used to refer to a member of the Supreme Court. However, the term "justice" is more commonly used when discussing the members of the Supreme Court. So, it would be more appropriate to say, "A justice of the Supreme Court is appointed by the president with the approval of the National Assembly."

2. In this context, it would be more appropriate to use the word "judge." When someone is removed from their position as a member of the judiciary, they are typically referred to as being "fired" as a judge. So, it would be more commonly said, "Both were fired after the incident/case."

3. Yes, the sentence "The new design will eventually replace all existing models" is grammatically correct. It means that the new design will gradually supplant or take the position of all the existing models.

4. The sentence "The new design will eventually take place of all existing models" is not grammatically correct. Instead, you can use the phrase "take the place of," as it implies that the new design will replace the existing models.

5. The sentence "The new design will eventually take the place of all existing models" is grammatically correct. This statement conveys that the new design will eventually supersede or replace all the existing models.

Instead of using the word "replace," you can also use phrases such as "substitute for," "supplant," "displace," or "take over" to express a similar meaning. For example, "The new design will eventually substitute for all existing models."
