The modern lowercase ‘g’ has two typographic variants: the single-storey (sometimes opentail) ‘g’ and the double-storey (sometimes looptail) ‘g’. The single-storey form derives from the majuscule (uppercase) form by raising the serif that distinguishes it from ‘c’ to the top of the loop, thus closing the loop and extending the vertical stroke downward and to the left. The double-storey form (g) had developed similarly, except that some ornate forms then extended the tail back to the right, and to the left again, forming a closed bowl or loop. The initial extension to the left was absorbed into the upper closed bowl. The double-storey version became popular when printing switched to “Roman type” because the tail was effectively shorter, making it possible to put more lines on a page. In the double-storey version, a small top stroke in the upper-right, often terminating in an orb shape, is called an “ear”.
