  2. Proto-Indo-European*en“in, into”
  3. Proto-Germanic*in“in”
  4. Old Englishin-“in, into”
  5. Middle Englishin-

  7. Latinin-“in, into”
  8. Old Frenchen-
  9. Middle Englishen-“en-, in-”
  10. Englishen-

From Middle English en- (“en-, in-”). Originally from Old French en- (also an-), from Latin in- (“in, into”) and Frankish *in-, *int-, *anda-; 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- and *in- (intensive prefixes), related to Old English on- and in- (intensive prefixes). More at in-, on-.
