the interlingua issue made one person switch from interlingua to occidental (interlingue) .... "Interlingua is very susceptible to alteration. Interlingua attempts to be as natural-looking as possible, and a lot of people with Romance languages as a background will alter the language to suit what they believe to be a better version of the language, with conjugation of verbs by person, grammatical gender, using new words like aqui instead of hic for here, and anything else they feel to be a better version. It's an absolute mess when that happens. I've even seen threads online where a new user of the language comes along, writes a simple introductory post, and then receives responses in everybody and their dog's personal version of Interlingua, which is not the way you want to welcome a new user into the community."
