I've just came across this article on the German Wikipedia [1] that defines towers and masts similar to our non-engineering definition mentioned above (translated with www.deepl.com/translator): > A tower is a vertically aligned structure which can be walked on and which is > defined by its height.

[1]: https://de.wikipedia.org/wiki/Turm There is a risk that towers and masts are defined differently in English, but perhaps Martin's idea to combine the two definitions would make sense nevertheless.
