en-

• em- (before certain consonants, principally b or p)

From Middle English en- (“en-, in-”). Originally from Old French en- (also an-), from Latin in- (“in, into”); but also from an alteration of in-, from Middle English in-, from Old English in- (“in, into”), from Proto-Germanic *in (“in”). Both the Latin and the Germanic forms are from Proto-Indo-European *en (“in, into”). Intensive use of Old French en-, an- is due to confluence with Frankish *an- (intensive prefix), related to Old English on- (intensive prefix). More at in-, on-.
