What does it mean to say "Terrell's relationship with David Ruffin was almost IRREPLACABLE"? "Irreplacable" is not a word. The word "irreplaceable" does not make sense as a substitute, since the sentence continues "[1], with some label mates and sources proclaimed that David Ruffin was responsible for Terrell's death". (Also, "proclaimed" is surely not the right form of this word, and "inappopriate" (from citation [1]) is also not right.) I'm not a wikipedia contributor, but maybe one of the 50 people who have worked on this page can do something.
