【Mountain】 , 【mount】 , 【peak】 , 【alp】 , 【volcano】 , 【mesa】 denote a relatively steep and high elevation of land.
【Mountain】 , the ordinary and inclusive term, varies somewhat in meaning according to locality. In general it designates an elevation higher and steeper than a hill, rising more or less abruptly from its surrounding country, and standing out conspicuously when viewed from a distance.
【Mount】 is often used in proper names of mountains.
【Peak】 , when applied to a 【mountain】 , designates one that rises to a sharp point; it may be isolated or one of a range.
【Alp】 suggests a towering, dizzy, or unscalable height.
【Volcano】 designates a cone-shaped 【mountain】 formed chiefly of ejected molten rock or ash and topped, usually, by a crater.
【Mesa】 is used especially in the southwestern part of the United States to designate a flat-topped elevation, usually comparable to a hill in height, but more suggestive of a 【mountain】 because of its steep clifflike sides.
