Occasionally a bisyllabic word is written with two characters that contain the same radical, as in 蝴蝶 húdié "butterfly", where both characters have the insect radical 虫. A notable example is pipa (a Chinese lute, also a fruit, the loquat, of similar shape) – originally written as 批把 with the hand radical, referring to the down and up strokes when playing this instrument, which was then changed to 枇杷 (tree radical), which is still used for the fruit, while the character was changed to 琵琶 when referring to the instrument. In other cases a compound word may coincidentally share a radical without this being meaningful.

Ah, so.. compound word

The Devonian spanned roughly from 419 to 359 Ma. The period was a time of great tectonic activity, as Laurasia and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidized iron (hematite) characteristic of drought conditions. Near the equator Pangaea began to consolidate from the plates containing North America and Europe, further raising the northern Appalachian Mountains and forming the Caledonian Mountains in Great Britain and Scandinavia. The southern continents remained tied together in the supercontinent of Gondwana. The remainder of modern Eurasia lay in the Northern Hemisphere. Sea levels were high worldwide, and much of the land lay submerged under shallow seas. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were Paleo-Tethys, Proto-Tethys, Rheic Ocean and Ural Ocean (which was closed during the collision with Siberia and Baltica).

The rivalry between Nintendo and Sega resulted in what has been described as one of the most notable console wars in video game history, in which Sega positioned the Genesis as the "cool" console, with more mature titles aimed at older gamers, and edgy advertisements that occasionally attacked the competition. Nintendo however, scored an early public relations advantage by securing the first console conversion of Capcom's arcade classic Street Fighter II for SNES, which took over a year to make the transition to Genesis. Despite the Genesis's head start, much larger library of games, and lower price point, the Genesis only represented an estimated 60% of the American 16-bit console market in June 1992, and neither console could maintain a definitive lead for several years. Donkey Kong Country is said to have helped establish the SNES's market prominence in the latter years of the 16-bit generation, and for a time, maintain against the PlayStation and Saturn. According to Nintendo, the company had sold more than 20 million SNES units in the U.S. According to a 2014 Wedbush Securities report based on NPD sales data, the SNES ultimately outsold the Genesis in the U.S. market.

Ah, so..
