The words "ia, tia; kial, tial; kiam, cxiam, neniam; kie, kiel, tiel;
io, kio, tio, cxio, nenio; kiu, cxiu, neniu", have already been met
with. They belong to a series whose use will best be seen from the
following examples:--

"ia" denotes kind or quality. "Kia" floro estas la plej bela? "Ia" kaj
"cxia" floro estas beta, "nenia" estas malbela. Mi admiras la rozon;
"tia" floro la plej placxas al mi. "What (kind of)" flower is the most
beautiful? "Any kind" and "every kind" of flower is beautiful, "no kind"
is ugly. I admire the rose, "that kind of" flower pleases me the most.

"ial", motive, reason. "Kial" li iros en Parizon? Mi ne scias; "ial"
li foriros, sed "cxial" estus pli bone resti en Londono. Li deziras
foriri, "tial" li foriros. "Why" is he going (will he go) to Paris?
I know not; "for some reason" he is going, but "for every reason" (on
every account) it would be better to remain in London. He wishes to go,
"therefore" (for that reason) he will go.

"iam", time. "Kiam" vi venos min viziti? "Iam" mi venos, "kiam" mi havos
libertempon; vi "cxiam" havas libertempon, mi "neniam". Postmorgaux
estos festo, "tiam" mi venos. "When" will you come to visit me?
"Sometime" I will come, "when" (at what time) I shall have a holiday;
you "always" (at all times) have a holiday, I "never" (at no time). (The
day) after to-morrow will be a festival (a general holiday); I will come
"then" (at that time).

"ie", place. "Kie" estas mia cxapelo? Gxi devas esti "ie", sed mi
sercxis gxin "cxie", kaj "nenie" mi povas trovi gxin. Ha, nun mi ekvidas
gxin "tie". "Where" is my hat? It must be "somewhere", but I have looked
