Frequently Asked Questions

Memory Aids
Mnemonic
Think of 'SEPT' like September (originally the 7th month in the Roman calendar) and 'ENNIAL' like in 'biennial' or 'centennial' (relating to years). So, 'septennial' = 'seven years'.
Conceptual Metaphor
TIME IS A MEASURABLE CYCLE. The word frames a segment of time (seven years) as a distinct, repeating unit, often for the purpose of organisation, evaluation, or celebration.
