What us Universities do have masters in syntax without gre?

There are very few, if any, universities in the US that offer Master's degrees in syntax *without* requiring the GRE. The GRE is a very common requirement for graduate programs in linguistics, including syntax, because it's used as a standardized measure of verbal reasoning and analytical skills, which are crucial for success in such demanding programs.

While some universities may be *considering* relaxing GRE requirements due to recent trends, or may have specific exceptions for exceptional applicants, it's highly unlikely you'll find a Master's in syntax program that explicitly states it *doesn't* require the GRE. You should always check the specific admissions requirements for each university's program. Don't assume a lack of mention of the GRE implies it's not required.
