Etymology
Etymology Information

'bacillariales' originates from Modern Latin, specifically the genus name 'Bacillaria' (from Latin 'bacillum' meaning 'little rod' or 'stick'), combined with the taxonomic suffix '-ales' that denotes an order.

Historical Evolution

'bacillum' (Latin, 'small rod') gave rise to the genus name 'Bacillaria' in biological Latin, and the plural/order-forming suffix '-ales' was later attached in Modern Latin to form the order name 'bacillariales'.

Meaning Changes

Initially the components referred to 'little rod' (bacillum) and a genus name; over time the combined form came to denote the formal taxonomic rank 'the order containing Bacillaria-like diatoms'.
