There are several crucial differences between Lojban and Loglan, two logical constructed languages. The main one is of the sounding of the core words, which, however, have similar phonotactics in both languages. Most grammatical particles also sound differently. Lojban alphabet lacks the letters q, w, h, but has the letter x and ' (apostrophe) (the last two absent in Loglan until 1977 for /h/ (spelled with an apostrophe) and x until 1986).
