[dml2135]

Uh, no, when you describe a pair you use the plural. “Pair of pants”, “pair of earrings”, “pair of socks” — these phrases do not refer to four of something.

[mannykannot]

You are right, though "pair of pants" is somewhat problematical as an example of this!

[pc86]

Dice is plural. Die is the singular.

[happymellon]

A pair of earrings.

Earrings is plural, earring is the singular.
