Ab vs. Abb: What's the Difference?

By Janet White & Aimie Carlson || Updated on May 30, 2024
"Ab" is a prefix meaning "away from" in Latin or shorthand for "abdominal" in English, while "Abb" is an abbreviation for "abbot" or "abbey" in religious contexts.

Key Differences

"Ab" is a prefix derived from Latin, meaning "away from" or "off." It is used in various English words such as "abstract," "abduct," and "abnormal." In a different context, "ab" can also be shorthand for "abdominal," referring to the muscles of the abdomen, often used in fitness terms like "ab exercises." "Abb" is an abbreviation used in religious contexts, standing for "abbot," who is the head of an abbey of monks, or "abbey," which is a complex of buildings used by members of a religious order. "Abb" is less common in general English usage compared to "ab."
"Ab" can also appear in scientific and medical terminologies, often indicating a relationship of separation or derivation. For instance, "absorb" (to take in), "absent" (away, not present), and "aberrant" (deviating from the norm). "Abb," by contrast, has a more specialized usage primarily within the context of religious institutions and is often seen in historical or ecclesiastical writings. It’s a shorthand notation and less likely to be encountered outside these specific contexts.
