YSITD_TG_Bot says to #ysitd<licson>: (@seadog007: 那Disf...) Dysfunction vs. Disfunction: dys- is a Greek prefix meaning "bad", "abnormal", "difficult", or "impaired". dis- is a Latin prefix with none of the above meanings. dys- has the right meaning, but function is a Latin word.at Wed, Sep 28, 2016 8:53 PM
