Abbreviations before/after names

Question

What are the more common abbreviations one might see printed before or after a person's name, and what do they mean? Please include honorifics (R'=Rabbi) as well as memorial - or prayerful - suffixes (eg., zt"l or shlit"a). I'm particularly interested in some of the lesser known ones that appear quite often, sometimes in connection with famous names and printed in the title page of Sefarim.

Answer 2

Then, too, we have to deal with some of the derogatory ones. A couple to start with:

י"ש or ימ"ש = yimach shemo

יש"ו = yimach shemam vizichram or yimach shimo vizichro (Great acronym by the way!)

שר"י = shem resha'im yirkav
