Key Differences

Considerable is used to describe something that is notably large in size, amount, or degree. It conveys that the subject is worthy of attention due to its size or extent but doesn't necessarily imply importance or impact. For instance, a considerable amount of money means a large sum, regardless of its effect on the situation. On the other hand, significant denotes that something is important, noteworthy, or consequential. It suggests that the subject has a meaningful impact or holds importance in its context. A significant discovery, for example, is one that has a profound effect on the field it pertains to.
When discussing quantities, considerable often quantifies the physical size or number, suggesting something that cannot be ignored because of its volume. In contrast, significant might refer to quantities too, but with an emphasis on the effect or value of the quantity rather than its sheer size. For example, a significant number of responses could be fewer than a considerable number but might have a greater impact on the outcome of a study.
In literature or spoken language, the use of considerable can imply that the speaker wishes to draw attention to the size or scope of an item or situation without asserting its importance. Whereas, using significant not only highlights the importance of the subject but also suggests that it has or could have a substantial effect or meaning behind it.
The choice between considerable and significant can also affect the tone or focus of a discussion. Describing an amount as considerable might simply aim to impress or inform about size, while calling something significant could provoke further inquiry into its implications or importance.
In research and scientific writing, the distinction becomes more pronounced. A considerable variation in data points might merely indicate a wide range of responses, while a significant variation implies that the difference observed has important implications or is statistically meaningful.
