Here are some synonyms for "sufficiently" along with an explanation of their usage:
1. Adequately
The word "adequately" means to a degree that is satisfactory or acceptable for a particular purpose. For example, "The room was adequately lit, so we could see clearly." It implies that the lighting was enough to meet the basic need of visibility. In a similar way to "sufficiently", it emphasizes that a certain condition or amount is sufficient to fulfill a function or requirement without going overboard.
2. Amply
"Amply" indicates an abundance or more than enough. For instance, "She was amply rewarded for her hard work." It shows that the reward was not just sufficient but was actually generous or plentiful. While "sufficiently" focuses on the idea of just enough, "amply" goes a step further to suggest a comfortable surplus. However, in many contexts, it can be used interchangeably with "sufficiently" when you want to emphasize that there is more than enough to meet a need.
3. Plenty
"Plenty" is a more informal term that means a sufficient or more than sufficient amount. For example, "There was plenty of food to go around." It gives the impression of a large quantity that is enough to satisfy everyone's needs. It's similar to "sufficiently" in that it conveys the idea of having an adequate amount, but it often sounds more casual and emphasizes the presence of a quantity that is more than just barely enough.
4. Enough
This is a very common and straightforward synonym. For example, "He had enough money to buy a new car." "Enough" simply means as much or as many as required. It is very close in meaning to "sufficiently" and is used in a wide range of contexts to indicate that a particular quantity or quality is sufficient to achieve a particular goal or meet a particular need.
5. Satisfactorily
"Satisfactorily" means in a way that meets expectations or requirements in a satisfactory manner. For example, "The problem was solved satisfactorily." It implies that the solution was sufficient to address the problem to an acceptable level. It is related to "sufficiently" because it also focuses on the adequacy of a particular action or condition to achieve a desired result.
