Poorly or something else?
Several adverbs sit close to poorly, and the difference is usually meaning rather than formality.
| badly | Stronger. Badly written is a harsher verdict than poorly written, which suggests weakness rather than failure. |
| inadequately | Formal, and specifically about not meeting a required standard. |
| weakly | About force or conviction rather than quality. |
The mistake to watch for
| Incorrect | Correct |
| He did poor in the exam. | He did poorly in the exam. |
Poor is an adjective and cannot describe a verb. Unlike fast or hard, it has no adverb use of its own.
A British complication. In British English poorly is also an adjective meaning unwell: she is poorly today. That use is unknown in American English, where it would be read as an incomplete sentence. If you are writing for a mixed audience, unwell or ill avoids the ambiguity.
