Yogh was an insular form of the letter "g" commonly found in Old English manuscripts. In appearance yogh was similar to the number "3". The name "yogh" is thought to derive from Old English words for "yew" or "yaw". When the French introduced the letter g after the Norman Conquest yogh shifted meaning and was used during the Middle English period to represent the sounds of the modern letters "gh" (as in "li3t"), "y" (as in "New 3ear"), and "z" (as in the name "McKen3ie"). Yogh gradually faded out of use in the late Middle English period because the English language already was using the letters "y" and "z" and "gh" was becoming more common, making yogh no longer necessary.
