In a manner relating to hearing or through the auditory sense; by listening rather than by seeing.
From auditory (relating to hearing/sound) + -ly (adverb suffix). Auditory itself comes from Latin audire (to hear), so auditorily means 'in a hearing/listening manner.'
When you learn something 'auditorily' you're learning by ear—this is why some people are auditory learners who need to hear information to understand it, unlike visual learners!
