The antonyms of "more transitional" are "less transitional" and "static". When something is less transitional, it means that it is more stable and less likely to change. On the other hand, static means something that is fixed and unmoving. When a situation or object is static, it lacks dynamism, and there is no room for adjustment or improvement. Both less transitional and static are essential concepts in understanding the degree to which change is possible, and they can be used to describe situations and objects in various contexts, such as in politics, economics, and technology. Consequently, the choice of antonym to use depends on the context in which the word "more transitional" appears.
