All the buildings in La Rinconada are high. And Colquechaca.
Granted, and probably not very tall.
But are mountains high or tall?
Definitely should be tall.
Same as all the other (relevant) items in this topic: imprecise use of language fails to convey meaning. I may have said this before: when the participants in a conversation can see context and body language, and interact to establish clarification where necessary, these fine points are not important. In written work (or a one-way voice channel) the precision use of words resolves potential ambiguities. If somebody says: "that man is 6 feet high", knowing that "high" is commonly misused one cannot tell whether he is standing on something that is 6 feet tall or the man is 6 feet tall himself. If I say "that man is 6 feet tall" you are sure which is meant, and if you are aware that the speaker will use "tall" when he means it, "that man is 6 feet high" now definitely means he is 6 feet up in the air. Language creep, in my opinion, is caused by the written word no longer being the primary means of mass communication.
If you built a building that looked like a mountain, would it be high or tall?
No difference, if we accept that "high" is a qualifier for the elevation of an object's base, and "tall" is a qualifier for its vertical extent.
And how about people? We talk about their height, not tallness.
Therein lies a challenge to my quest for tidiness. The engineering dimensions are length, width, height, and depth, when their equivalent qualifiers are long, wide, tall, and deep.
