+1 for the information, but I don't think all the "Augh"s are warranted.

One of the widely accepted, dictionary definitions of "cement" is simply "concrete." (In fact, Merriam Webster has this listed as definition #1.) I understand that the terms have different technical meanings, but in common English they are simply synonyms.

E.g., http://www.merriam-webster.com/dictionary/cement

There may be an opportunity for a Battle of the Dictionaries here, but I think this skirmish in the language wars may be over.

Fair enough :/ it just feels like 'misusing' words is disrespectful to their source, as though a lack of effort was taken to use it 'properly' (air quotes since those are highly subjective terms). In a detached sense, I suppose seeing semantic change [1] in action is neat, but it is still just the tiniest bit depressing.

edit: Ah! Also cool is dental cement [2] which is, as the name would imply, used in dentistry (but without any aggregate equivalent!).

Totally agree. Even if "concrete" and "cement" can "properly" be used interchangeably, I myself prefer to use words in a way that recognizes these sorts of distinctions. It keeps language more information rich and historically connected. (And keeps me from being looked down upon by well-educated people who, like myself, incline towards language snobbery :))
