Chapter 3: The Hills Are Alive With The Sounds Of Lojban
7. Initial Consonant Pairs
The set of consonant pairs that may appear at the beginning of a word (excluding Lojbanized names) is far more restricted than the fairly large group of permissible consonant pairs described in c3-§6. Even so, it is more than English allows, although hopefully not more than English-speakers (and others) can learn to pronounce.
There are just 48 such permissible initial consonant pairs, as follows:
- bl br cf ck cl cm cn cp cr ct dj dr dz fl fr gl gr jb jd jg jm jv kl kr ml mr pl pr sf sk sl sm sn sp sr st tc tr ts vl vr xl xr zb zd zg zm zv
Lest this list seem almost random, a pairing of voiced and unvoiced equivalent vowels will show significant patterns which may help in learning:
pl pr fl fr bl br vl vr cp cf ct ck cm cn cl cr jb jv jd jg jm sp sf st sk sm sn sl sr zb zv zd zg zm tc tr ts kl kr dj dr dz gl gr ml mr xl xr
Note that if both consonants of an initial pair are voiced, the unvoiced equivalent is also permissible, and the voiced pair can be pronounced simply by voicing the unvoiced pair. (The converse is not true: “cn” is a permissible initial pair, but “jn” is not.)
Consonant triples can occur medially in Lojban words. They are subject to the following rules:
- The first two consonants must constitute a permissible consonant pair;
- The last two consonants must constitute a permissible initial consonant pair;
- The triples “ndj”, “ndz”, “ntc”, and “nts” are forbidden.
