It would be the root word "C. Ambi-" that means “more than one”, since this is often used in the English language in words such as "ambidextrous"--meaning to have full use and ability in both hands.
Harappan Civilization's writing has never been decoded. Harappan Civilization is a part of the Indus Valley Civilization. The languages of the Harappan Civilization belong to the Bronze Age and they are still today a mystery. This language is totally unattested to any source that is readable. This is one mystery that is yet to be solved.
The Radical Republicans were a faction of American politicians within the Republican Party of the United States from around 1854 (before the American Civil War) until the end of Reconstruction in 1877. They called themselves "Radicals" and were opposed during the War by the Moderate Republicans (led by President Abraham Lincoln), by the conservative Republicans, and the largely pro-slavery and later anti-Reconstruction Democratic Party, as well as by conservatives in the South and liberals in the North during Reconstruction.[1] Radicals strongly opposed slavery during the war and after the war distrusted ex-Confederates, demanding harsh policies for punishing the former rebels, and emphasizing equality, civil rights, and voting rights for the "freedmen" (recently freed slaves).[2]
During the war, Radical Republicans often opposed Lincoln in terms of selection of generals (especially his choice of DemocratGeorge B. McClellan for top command of the major eastern Army of the Potomac) and his efforts to bring seceded Southern states back into the Union as quickly and easily as possible. The Radicals passed their own reconstruction plan through the Congress in 1864, but Lincoln vetoed it and was putting his own presidential policies in effect by virtue as military commander-in-chief when he was assassinated in April 1865.[3] Radicals pushed for the uncompensated abolition of slavery, while Lincoln wanted to pay slave owners who were loyal to the Union. After the war, the Radicals demanded civil rights for freedmen, such as measures ensuring suffrage. They initiated the various Reconstruction Acts, and limited political and voting rights for ex-Confederate civil officials, military officers and soldiers. They bitterly fought President Andrew Johnson; they weakened his powers and attempted to remove him from office through impeachment, which failed by one vote in 1868.
