Grog This was the sailors' term for watered rum. In 1740, Admiral Vernon ordered water to be added to the rum that was issued to men of the Fleet. As can be understood, this particular order was not popular with the crews. The Admiral was in the practice of wearing clothes made from a material called 'grogham'. Thus, his nickname became 'Old Grog', and so it became the name for the beverage issued to the sailors.
Mess Comes from the Latin word 'mensa' meaning a table or the Gothic 'mesa' meaning a dish of food.
Messmates Sailors eating from the same mess or at the same table. The sailor is always loyal and true to their messmates. Mufti These were an official class of men in India who at that time, interpreted the law. Known throughout India as Muftis', they dressed in civilian attire, unlike many other civil servants of the day. So, when a naval officer shifted out of uniform into civilian clothes to proceed ashore, it was spoken of as shifting into 'mufti'.
