Funlang

A funlang is a 'just for fun' conlang. Of course, many conlangs - including many famous and ambitious ones - are made just for fun. In this sense, Quenya and Sindarin are funlangs. More specifically, a funlang is a small conlang project done without much afterthought or high aspiration, as a distraction from more 'serious' conlang projects. A funlang in this sense usually has no detailed conculture or conhistory attached, the grammar is and will remain sketchy, the vocabulary is small, etc. It is done without much effort.
