Which word means something added to another thing but not essentially part of it?

• A. Adjunct
• B. Incumbent
• C. Blatant
• D. Erratic

Answer: (A)

Something added to another thing but not essentially part of it is described by the word adjunct. An adjunct is a supplementary piece that attaches to the main thing to help or enhance it without becoming its core part. For example, an adjunct professor is someone brought in to teach part-time and support the department, not a full, essential member of the faculty.

The other terms don’t fit this sense. Incumbent refers to the current holder of a position or something necessary that remains in place, rather than an optional addition. Blatant means obvious or conspicuously wrong, and erratic means unpredictable or inconsistent—neither describes an added, nonessential component.
