My conlang is very literal to human perception, and I continued building vocabularies for physical quantities.
Though in a previous question, I brought an exotic trick to describe length (namely, give "red" for "long" and "violet" for "short"), I eventually found that, the presence of multiple eyes should exactly measure the usual length between two spatial points. Simple geometry and trigonometry; the distance between the two eyes and the four angular distances should give the said length exactly.
I took this further. Perhaps my conlang should use the same words when the quantities have the same physical dimension, only differentiated by the following adverb. This idea would be demonstrated in English like this:
- high = long up / low = short up
- deep = long down / shallow = short down
- far = long in front / close = short in front
- wide = long between / narrow = short between
Does any natural language do this?
