## Equivalence

neck and neck Even, equal, on a par; abreast, at the same pace. Based on available citations, figurative use of this expression is as old as the literal horse-racing one, both dating from the early 19th century. It still finds frequent application.

Production ran neck and neck in the studios, but the second version … reached the public screen last. (The Times, June, 1955)

nip and tuck So close as to be of uncertain outcome; neck and neck, on a par, even; up in the air, questionable. This chiefly U.S. term is of puzzling origin and inconsistent form, appearing in print in the 1800s as rip and tuck, nip and tack, and nip and chuck, before assuming its present nip and tuck. Its original restriction to contexts describing close contests, usually athletic, lends credence to the claim that it originated as a wrestling term (Barrère and Leland, Dictionary of Slang, 1890). The expression is now employed in much broader contexts, indicative of any kind of uncertainty.

It is nip and tuck whether such a last great achievement of the bipartisan foreign policy can be ratified before … the Presidential race. (The Economist, May, 1948)
