Jes, sed neniu parolas lojbanan en la reala mondo. ;)

Silly slashdot. atas = sxatas (that should be a circumflex over the s, but UTF-8 support is either lacking from the forum or my browser messed it up.)

Nope, no noun declensions. Nouns are made by adding -o to the end of a root. The only changes that are made to a noun are for number or case, and this is done through agglutination instead of declension. Plurals are formed by adding -j after -o. The accusative (direct object) case is made by adding -n after the -o (or after the -j in case of a plural). (j is pronounced like y in Esperanto).

All of these sentences say "I like to learn new languages", although the first one is by far the most common form:

Mi atas lerni novajn lingvojn.
Novajn lingvojn mi atas lerni.
Novajn lingvojn atas lerni mi.
Lerni novajn lingvojn mi atas.
Lerni novajn lingvojn atas mi.
