The word "de-ranging" is not widely used, and therefore it doesn't have any established antonyms. However, if we were to look at its meaning "to go astray or become disordered," we could come up with some possible antonyms. These may include words like "organized," "disciplined," "in order," "regimented," "methodical," "systematic," and "structured." Choosing an appropriate antonym for de-ranging would depend on the context in which it is used, as well as the specific meaning that is being conveyed. In general, though, any word that implies order and coherence could be considered an antonym for de-ranging.
