Feedback Please,....

Hi,
Many of the designers on this platform are non-English natives. I, on the other hand, am an English native, however, I'm trying to understand your allusion to "isotypes." The dictionary definition of isotypes is diverse. Can you please expand on what you have in mind relating to NT "isotypes" please? Your understanding regarding this matter is appreciated. Thank you.
