Nyms (1)
1. Contronyms is a single word that has multiple meanings that contradict the others– Examples:
• Fast - moving quickly vs. firmly stuck in place• Hysterical - overwhelmed with fear vs. outrageously
funny
2. Heteronyms are words that are spelled identically but have different meanings when pronounced differently:– Examples: bow, desert, object
3. Polyonyms are different words have the same meaning – Examples: Jupiter, Zeus, Oden

Nyms (2)
4. Homonyms are words that have the same sound but a completely different meaning
– Examples: to, too, two– Comment: Some homonyms are also
contronyms
5. Capitonym is a word that changes pronunciation and meaning when it is capitalized.
– Examples:• You polish silver with ammonia and silicon, though
you'd never dream of applying the same to a Polish sausage.

6. Caconym is an erroneous name, especially in taxonomic classification.
– Caconyms might be useful for tracking down archaic or outdated usage but misleading otherwise.
7. Exonym is a place name that foreigners use instead of the name that natives use.
– Examples: Cologne:Koln; Morocco:Maroc.– Using exonyms as search terms will likely
net results biased toward foreign information
