What's the difference between i.e. and e.g.?
mid-14c., comenden, from Latin commendare "to commit to the care or keeping (of someone), to entrust to; to commit to writing;" hence "to set off, render agreeable, praise," from com-, intensive prefix (see com-), + mandare "to commit to one's charge" (see mandate (n.)). In some senses, a shortening of recommend. Related: Commended; commending.
