Learning
Memory Aids
Mnemonic
Think 'NONA' has 'NINE' letters if you count the 'I' as a Roman numeral I (which is 1), and the rest spell 'NO A' (sounds like 'no eh?' – forget it, just remember it's like 'NONAgon' a 9-sided shape).
Conceptual Metaphor
QUANTITY AS CONTAINER / SHAPE (e.g., nonagon as a container with nine sides).

FAQ
Frequently Asked Questions
No, 'nona-' is a prefix. It must be attached to another word root (e.g., nonagon, nonagenarian).
Both mean 'nine'. 'Nona-' is Latin-derived, 'ennea-' is Greek-derived. Usage depends on the linguistic origin of the word root it's attached to (e.g., nonagon vs enneagram).
In British English: /ˈnəʊnə-/. In American English: /ˈnoʊnə-/. The stress is on the first syllable.
Yes, 'Nona' can be a female given name (from Latin meaning 'ninth'), but this is distinct from the prefix and is a separate lexical item.
