Learning
Memory Aids
Mnemonic
Imagine a DIPLOMA (certificate) given to a pair (diplo-) of BAs (like students) who are shaped like rods (bacilli) and are always together. So, DIPLO-BA-cilli = DIPLOBACILLUS.
Conceptual Metaphor
PAIR OF STICKS / TRAIN CARRIAGES: Conceptualized as two identical rod-shaped units linked together, like two sausages end-to-end or a short train of two carriages.
