Would 'fast dreadnought' clarify battleship terminology?

Should First World War fast battleships be called fast dreadnoughts to distinguish them from Second World War ships?

No. The additional label would create more confusion, especially because several First World War designs remained fast battleships in later service.

The proposed term tries to distinguish early fast capital ships from later fast battleships. The extra label would make an already disputed classification system harder to follow. Some fast ships designed in the First World War also served through the Second, so a period-specific name would create overlap rather than a clean dividing line.
