Again, the native word is sometimes less emphatic than the classic: 

LIST D

fly, soar             old, venerable         flood, cataclysm
steep, precipitous    wonder, astonishment   speed, velocity
sparkle, scintillate  stir, commotion        stir, agitate
strike, collide       learned, erudite       small, diminutive
scare, terrify        burn, combustion       fire, conflagration
fall, collapse        uproot, eradicate      skin, excoriate
hate, abominate       work, labor            bright, brilliant
hungry, famished      eat, devour            twisted, contorted
thin, emaciated       sad, lugubrious        mirth, hilarity

Despite these exceptions, the native word is in general better known and more crudely powerful than the classic.  Thus of the pair sweat-perspiration, sweat is the plain-spoken, everyday member, perspiration the polite, even learned member.  The man of limited vocabulary says sweat; even the sophisticated person, unless there is occasion to soften effects, finds sweat the more natural term.  No one would say that a horse perspires.  No one would say that human beings must eat their bread in the perspiration of their faces.  But sweat is a word of connotation too vigorous (though honest withal) for us to use the term in the drawing room.  A questionable woman in The Vicar of Wakefield betrays her lack of breeding by the remark that she is in a muck of sweat.

The native word, besides being in itself simpler and starker than the classic, makes stronger appeal to our feelings and affections.  In nearly every instance the objects and relationships that have woven themselves into the very texture of our lives are designated by native terms.  Even if they are not so designated solely, they are so designated in their more cherished aspects.  We warm more to the native fatherly than to the classic paternal.  We have a deeper sentiment for the native home than for the classic residence.

That the native is the more downright term may be seen from the following words. (These pairs are of course merely illustrative.  With them might be grouped a few special pairs, like devilish-diabolical and church-ecclesiastical, of which the first members are classic in origin but of such early naturalization into English that they may be regarded as native.)
