CONSONANTS.
3. The consonants b, d, f, h, k, l, m, n, p, t, v, z, are pronounced as in English, and the remaining eleven as follows:
c like ts in hats, tsetse.
ĉ like ch in chin, much.
g like g in go, big.
ĝ like g in gem, j in jar.
ĥ is produced by expelling the breath forcibly, with the throat only partially open.
As in pronouncing German and Scotch ch, Spanish j, Irish gh, Russian x, Classical Greek χ etc. There are only a few words containing this consonant.
j like y in yes, beyond.
