There are three kinds of lerpoi that satisfy those properties but aren't
brivla: tosmabru, slinku'i, and invalid lujvo. A lerpoi beginning with a
consonant cluster and the result of prepending a cmavo to it cannot both be
brivla; either the shorter is a slinku'i, or the longer is a tosmabru (or the
cmavo has more than three letters). (I am using "tosmabru" loosely.) The set
of strings that satisfy those properties and are not tosmabru or slinku'i, I
call greater brivla space. Strings in greater brivla space that aren't brivla
are invalid lujvo. There are two kinds: errors of hyphenation (lekymoi) and
errors of rafsi (lekybumoi).
