148: Antennae versus Antennas May 5, 2015

Although the most common way to pluralize nouns is ab adding '-(e)s', this is not the only way: some are created by adding '-a', some by adding 'ae', and plenty others. This becomes tricky with words such as 'antenna'. In standard English, American, and Canadian writing, 'antenna' as in the organ of an insect is pluralized, 'antennae', and the mechanical apparatus pluralized is 'antennas'. This rule does not apply to Austral writing, as the spelling is interchangeable.
