Syn: Neat; concise; compact.
Usage: Terse, Concise. Terse was defined by Johnson "cleanly written", i. e., free from blemishes, neat or smooth. Its present sense is "free from excrescences," and hence, compact, with smoothness, grace, or elegance, as in the following lones of Whitehead: [1913 Webster]
"In eight terse lines has Phaedrus told (So frugal were the bards of old) A tale of goats; and closed with grace, Plan, moral, all, in that short space." [1913 Webster] It differs from concise in not implying, perhaps, quite as much condensation, but chiefly in the additional idea of "grace or elegance."
