In a way that relates to the atmosphere or is light and airy.
The dancers moved aerily across the stage, as if floating on air.
The word 'aerily' is derived from 'aerial' (from Latin 'aerialis', meaning pertaining to air) and the adverbial suffix '-ly' (meaning in a manner of). Thus, 'aerily' means in a manner pertaining to or characteristic of the air.
Imagine something that is 'of the air' ('aerial') and how it moves 'in a manner' ('-ly') that reflects that quality. This helps you remember that 'aerily' describes something done in an airy or ethereal way.
