Some make a distinction between an (term) and an (aerial), with the former used to indicate a rigid structure for radio reception or transmission, and the latter consisting of a wire strung in the air. For those who do not make a distinction, (term) is more commonly used in the United States and (aerial) is more commonly used in the United Kingdom.
For the faculty of intuitive astuteness, the Latinate plural is used most frequently but both forms are found.
