Check Icon Analysis

To ‘perturb’ is to annoy, confuse, or generally unsettle somebody. In a number of ways, it is very similar to the word ‘disturb’, and can be used as a more formal substitute for it in most contexts. It is much more likely to be encountered in written, rather than spoken English. The term ‘unperturbed’ is its exact opposite.
