Definition

1. Conjunction:
   • Suppose that, if, assuming that: Used to introduce a hypothetical situation or condition for the purpose of discussion, argument, or illustration. It sets up a premise that may or may not be true to explore its potential consequences or logic.

Usage Examples

• Conjunction:
  • Giả dụ anh ấy đến muộn, chúng ta nên làm gì? (Suppose he arrives late, what should we do?)
  • Giả dụ trời mưa, buổi dã ngoại sẽ bị hủy. (If it rains, the picnic will be canceled.)
  • Hãy giả dụ bạn có một triệu đô la. Bạn sẽ làm gì? (Let's assume you have a million dollars. What would you do?)

Advanced Usage

• "Giả dụ như": A slightly more emphatic or formal variant meaning "suppose that" or "assuming that".

  • Giả dụ như kế hoạch đó thất bại, chúng ta có phương án dự phòng không? (Assuming that plan fails, do we have a backup option?)

• Used in logical or mathematical reasoning: To set up a conditional premise.

  • Giả dụ A bằng B và B bằng C, vậy thì A bằng C. (Suppose A equals B and B equals C, then A equals C.)

Variants and Related Words

  • Giả sử ngày mai là tận thế... (Suppose tomorrow is the end of the world...)
