N.B.—No title beyond his rank is given to a General in England, like "Monsieur le General" in France. We usually say "General," or "Sir," but moŝto might be used in Esperanto.

(d). As regards addresses of letters, we can say:—

284. Suffixes -OBL-, -ON-, -OP-. (Ex. [18].) These three suffixes are used with numerals, making them multiples, fractions, or collectives (see pars. [119], [120], [121]).

(a). -OBL- added to a cardinal number denotes the number is a multiple. It is equivalent to the English suffixes "-fold" or "-uple."

Examples.—Multoblo = a multiple, multobla = manifold. Unu = one, unuobla = single, unuoble = singly. Du = two, duobla = double, la duoblo = the double. Kvar = four, kvarobla = fourfold, quadruple, la kvaroblo = the quadruple. Cent = hundred, centoblo = a centuple. It is used in the multiplication table:—

kvaroble tri estas (or, faras) dek du4 times 3 = 12
kvinoble kvar estas dudek5 times 4 = 20
sesoble kvin estas tridek6 times 5 = 30
sepoble ses estas kvardek du7 times 6 = 42
okoble sep estas kvindek ses8 times 7 = 56
naŭoble ok estas sepdek du9 times 8 = 72
dekoble naŭ estas naŭdek10 times 9 = 90
dek-unuoble dek estas cent dek11 times 10 = 110
dek-duoble dek unu estas cent tridek du12 times 11 = 132

(b). -ON- added to a cardinal number denotes a fraction. As a root, ona = fractional.

Examples.—Du = two, duona = half, duone = by halves, duono = a half (1⁄2). Tri = three, triona = third, triono = a third (1⁄3). Kvar = four, kvarona = quarter, kvarono = a fourth (1⁄4). Dek = ten, dekona = tenth, dekono = a tenth (1⁄10), tri dekonoj = 3⁄10ths. Dek du = twelve, dek-duona = twelfth, dek-duono = a twelfth (1⁄12), kvin dek-duonoj = 5⁄12ths. Sesdek kvin centonoj = sixty-five hundredths (65⁄100). La kvinona parto (la kvinono) de cent estas la triona parto (la triono) de sesdek, tio estas dudek = The 5th part of 100 is the 3rd part of 60, that is 20.
