Di*gam"ma (?), n. [Gr.
&?;; &?; = &?; twice + ga`mma the letter Γ. So called because it resembled two gammas placed one above the other.]
(Gr. Gram.)
A letter (&?;, &?;) of the Greek
alphabet, which early fell into disuse.
&fist; This form identifies it with the Latin F, though in sound it is said to have
been nearer V. It was pronounced, probably, much like the
English W.
