Sometimes the world seems a bit like alphabet soup. There are organizations that function by acronym alone (such as NJOP -- the National Jewish Outreach Program, not to be confused with AJOP the Association for Jewish Outreach Programs). There are also the ever increasing abbreviations that are being made popular via texting (e.g. “ttyl”-talk to you later, and “imho”-in my humble opinion). And one can hardly ignore the various titles that appear in abbreviated form following a person’s name (e.g. PhD, MD, JD, MBA).
Judaism also has a range of abbreviations that follow a name. Many see these abbreviations all their lives without ever knowing exactly what they mean. Perhaps the most common are those abbreviations that are used to honor the dead.
The three most frequent honorific abbreviations are: Z”L, O.B.M. and A”H. Z”L is an acronym for the Hebrew words zichrono/zichrona liv’racha (male/female), most often translated as “May his/her memory be blessed.” “Of Blessed Memory” is succinctly abbreviated as O.B.M. A”H is the abbreviation for alav/aleha hashalom, which is translated as “May peace be upon him/her.”
For righteous individuals, such as great rabbis and leaders, the abbreviation ZT”L, zecher tzaddik liv'racha, is often used. It means, “May the memory of this righteous person be a blessing.”
These terms are added both when writing and/or talking about an individual. Not only does it inform people that the person is no longer living, but is also a way of bringing blessing upon the memory and the soul of the deceased.
