Editing Caltrop (section)

==Name==
The modern name "caltrop" is derived from the Old English {{lang|ang|calcatrippe}} (heel-trap),<ref>{{cite web |url=http://www.merriam-webster.com/dictionary/caltrop |title=Definition of Caltrop |website=www.merriam-webster.com |access-date=2 April 2018}}</ref><ref>{{cite web |url=https://www.dictionary.com/browse/caltrop |title=Definition of Caltrop |website=www.dictionary.com |access-date=21 March 2021}}</ref> such as in the French usage {{lang|fr|chausse-trape}} (shoe-trap). The Latin word {{lang|la|[[tribulus]]}} originally referred to this and provides part of the modern scientific name of a plant commonly called the caltrop, ''[[Tribulus terrestris]]'', whose spiked seed cases resemble caltrops and can injure feet and puncture bicycle tires. This plant can also be compared to ''[[Centaurea calcitrapa]]'', which is also sometimes referred to as the "caltrop". ''Trapa natans'', a water plant with similarly shaped spiked seeds and edible fruit, is called the "[[water caltrop]]".
