Many confuse “assent” and “ascent” because they sound the same.
Assent means agreement, while ascent means rising or climbing. Using the wrong word can change your sentence’s meaning like saying “He gave his ascent to the plan” instead of “assent.”
This guide quickly explains the difference, with examples, tips, and easy rules to always use the right word.

Ascent (noun): The act of rising, climbing, or moving upward.
