The word 'ancillary' means something that is helpful or supportive but not the main thing. An example sentence could be, "The ancillary staff at the hospital includes janitors and receptionists who help the doctors and nurses take care of the patients." So, 'ancillary' describes things that are not directly related to the main thing or task, but still play a supportive role in helping it to function smoothly.
