So I was doing a bit of writing and ended up using the phrase "long-thought" (as in, "a technique long-thought forgotten" or "people long-thought incapable of using magic"). I ended up using it quite a few times and was wondering if anyone can come up with another phrase with the same (or a very similar) meaning so that I won't constantly be using the same word. Thanks to anyone who can help!
Received knowledge was that Trump was not a serious candidate.
I learned this phrase from listening to BBC news programs. It means what was popularly believed.
You can also use that: popularly believed. For example:
At one time, it was popularly believed that Mars was criss-crossed with canals.
The common or popular conception was that etc.
You can also try
people previously thought [to be] incapable of using magic
In other words, leave out "long." (This "to be" is optional.)
