Here's a breakdown:
* Thought: Indicates that this is an opinion or assumption, not a confirmed fact.
* Stabilized: Means that something has become stable or settled, no longer changing or fluctuating.
Examples:
* "The patient's condition is thought to have stabilized after the surgery."
* "The stock market, which had been volatile for weeks, is thought to have stabilized."
* "The political situation in the region is thought to have stabilized after the recent elections."
Essentially, "thought to have stabilized" means that something is likely no longer changing, but it's still possible that the situation could change again in the future.
