Syn: High; lofty.
Usage: Tall, High, Lofty. High is the generic term, and is applied to anything which is elevated or raised above another thing. Tall specifically describes that which has a small diameter in proportion to its height; hence, we speak of a tall man, a tall steeple, a tall mast, etc., but not of a tall hill. Lofty has a special reference to the expanse above us, and denotes an imposing height; as, a lofty mountain; a lofty room. Tall is now properly applied only to physical objects; high and lofty have a moral acceptation; as, high thought, purpose, etc.; lofty aspirations; a lofty genius. Lofty is the stronger word, and is usually coupled with the grand or admirable. [1913 Webster] Tallage
