Ancillary refers to something that provides necessary support to the primary activities or operation of an organization, system, etc., while auxiliary is providing additional or supplementary support or help.
Ancillary vs. Auxiliary

Key Differences

Ancillary services or products are those that support the primary function of a business or system, often seen as secondary yet essential components. Auxiliary means providing supplementary or additional help and support, often to enhance a primary function.

In a hospital, ancillary services like cleaning and catering are crucial to its operation, but they aren't part of the core medical services. An auxiliary power unit in an aircraft, however, provides additional power and is not the main power source.

The term ancillary often implies a subordinate role that, while supportive, is not central to the main function. Auxiliary, in contrast, suggests a role that enhances or supplements the primary function, often to increase efficiency or capability.

For example, ancillary staff in a law firm, such as paralegals and administrative assistants, play supporting roles to the primary activities of lawyers. An auxiliary police force, on the other hand, supports and enhances the regular police force, but is not a replacement for it.

Ancillary can also describe services in education, like counseling and library services, that support the primary educational mission. Auxiliary often refers to additional groups or equipment, like auxiliary engines on a boat, which provide supplementary support.
