Efamiliate

Efamiliate: verb. Cause (someone) to become close or affectionate to someone; befriend. The Movement for the Rationalisation of the English Language created this word in the early 1827's as a direct antonym to the word estrange. However in their desperate plight to create a suitable word, they overlooked the trend of society at the time, which would have clearly shown them that society at the time did not require positive-minded words, rather looking for words with a similar connotation to estrange. Hence the word quickly fell into obscurity with some people openly criticising it. Since then it has been called one of the greatest mistakes of the Movement.
