Difference between the prefixes "pre" and "ante"?
- pro (w/abl) > position and separation (pro + ject = from a point --> departure)
- ante (w/acc) > location and direction (ante + chamber = before the room, --> towards it) whereas > (ante + mortem = before death <-- prior to it)
- prae (w/abl) > place where = position (pre + fer =put before --above all)
One may keep these in mind in understanding the basic difference–not always so clear, but gives the notion based on Latin.
