I'll be right back. Wow, I'm reading, knowing something about Loglan.

As said by the Lojban Group and the law, Lojban is equal to Loglan.

The father of the conlang Lojban is Loglan.

It is the 6th of July of 2013. According to Arika Okrent, the writer of In the Land of Invented Languages, Lojban has the most complete grammar of any conlang. Lojban's father was Loglan, which started development in 1955. Lojban began its development in 1987 by a professional staff. In 1997, it was "baselined" or frozen, lasting 5 years until 2002 when speakers became free to create new words and idioms and decide which way the language is heading. The Purple Dream is reality.

The Loglan formal grammar is made up of 91 CFG-type rules.

Loglan is an isolating language, much like English. That means that once you’ve learned a word, you don’t have to worry about changing its form. Even in English, you have to remember to add ‘-ed’ to a verb to make it refer to the past, and ‘-s’ to nouns to make them plural. In Loglan, you won’t have to do that. Also, some English verbs and nouns have irregular forms. There are no irregular Loglan forms.

Typically, the people who develop Romanization systems (or constructed languages like Loglan or Iqglic they'll want their alphabet to minimize surprises so that it's easy to learn. So they'll typically choose letter-sound correspondences from existing languages. Though, they don't necessarily take all of their letters from the same language (which may be your source of confusion).
