The word "more encroaching" means to intrude or encroach further. However, its antonyms would be words expressing a lack of intrusion or encroachment. Such antonyms could include "yielding," "retreating," "receding," "retracting," "withdrawing," "relinquishing," "relenting," "surrendering," "abdicating," or "submissive." These words imply a sense of concession or backing off. When used in the context of encroaching, they can illustrate a situation where one party ceases to infringe on the territory or rights of another. Thus, rather than encroaching, these antonyms signal a movement towards conciliation and compromise.
