two in a group?

Question

we have the word 'trio' for three in a group, what's the ONE word for two in a group?

Answer 1

duo

Answer 2

a pair

Actually, the others are correct. Duo would be what you'd call a musical group, etc., but since this was in the Education forum, I was thinking like a teacher, and I put my students in groups of three or four, or in pairs.

Answer 3

Of course there is duo, as in the "Dynamic Duo" of Batman and Robin. However, there is also "dyad":

dy·ad - n.
Two individuals or units regarded as a pair: the mother-daughter dyad.
Biology. One pair of homologous chromosomes resulting from the division of a tetrad during meiosis.
Chemistry. A divalent atom or radical.
Mathematics.
A function that draws a correspondence from any vector u to the vector (v·u)w and is denoted vw, where v and w are a fixed pair of vectors and v·u is the scalar product of v and u. For example, if v = (2,3,1), w = (0,-1,4), and u = (a,b,c), then the dyad vw draws a correspondence from u to (2a + 3b + c)w.
A tensor formed from a vector in a vector space and a linear functional on that vector space.
adj.
Made up of two units.
