| Common mistakes | Confused with 'considering' as a verb instead of 'considerable' as an adjective., Using 'considerable' with uncountable nouns only, instead of also with countable., Omitting it when it can emphasize significant amounts. | Mixing up with 'negligible' and using it in the wrong context., Using 'not negligible' to describe minor issues., Assuming it can be used without context for clarity. |
| Usage notes | Use 'considerable' when discussing something important or substantial. It's appropriate in both written and spoken language, but avoid using it in very casual contexts. | Use 'not negligible' when discussing facts or figures that matter significantly. It's suitable for academic, technical, or formal contexts but may sound overly complex in casual conversation. |
