6/10    Can "obaachan" in Japanese mean grandmother?  I thought grandmother is
        "obaasan", but someone told me it's "obaachan".  Thx.
        \_ AFAIK they are both grandmother.  They differ in levels of
           familiarity/respect.
           \_ Thx. -- OP
        \_ "-san" is an honorific; "-chan" is more of an affectionate term.
           "obaa" is the base term meaning grandmother; colloquially, it can
           also mean "old woman," though you would only use the base without
           an honorific if you were being rude. To be really rude, you could
           even skip the initial honorific "o-" and substitute a curse-word:
           "kuso baabaa" = "shitty old bitch." Then run. --erikred
           \_ hahahaha funny. How about the store "Obaji" where a bunch
              of old women go to get their facials done?
              \_ Perhaps you mean: http://www.obagi.com ?
                 Also, the base term for grandfather is "ojii-"; hence the
                 same for "old man," which is why all the kogaru call you
                 "sukebe jiijii!"
