Expert writing Tips
Best practice
When using "let suppose that", clearly define the conditions or parameters of your hypothetical scenario to avoid ambiguity.
Common error
Avoid using "let suppose that" when a simple "suppose that" or "let's assume that" is sufficient. The inclusion of both "let" and "suppose" can sometimes create unnecessary wordiness.

"Let suppose that" and "suppose that" are largely interchangeable, though "let suppose that" can feel slightly more conversational. "Suppose that" is a bit more direct.
Can I use "let's suppose that" instead of "let suppose that"?

In academic contexts, consider using more formal alternatives like "let us assume that", "assuming that", or "on the assumption that" to maintain a professional tone.
