I'm looking for a single word (if possible) to express the idea of first establishing/attaining a state and then maintaining it (not breaking it or letting it deteriorate).
The word could be applied to any subject, but one example might be the idea of establishing then maintaining mutual trust in a relationship. Perhaps the word could also feasibly apply to things, such as acquiring an object/possession and then keeping it in good shape.
This term would be paired with whatever state or object is the subject of this term. Not sure if it would technically qualify to be a hypernym, if such a term exists, but it sounds like it might.
