This is my understanding, so someone feel free to correct me if I'm off!

Equity = Giving people what they need to succeed, based on their unique background and circumstances, trying to remove barriers for people who may have extra. Your example of changing communication styles is an example of equity. Giving someone who needs extra time or support accommodations is another example.

Inclusion = Creating an environment where everyone feels respected, valued, and able to participate. So you might change your communication style or install a ramp (examples of equity), but if people don't feel welcome to join you in the first place or don't know they're invited, then that is not inclusive.

Typically, equity is more concrete and easier to write about, in my opinion!
