Gnomish

Gnomish is the language of the Gnomes and is often noted as a language of academia and secrecy. Gnomish utilises a technique known as 'double term' in which two conversations can be held simultaneously due to variations of meaning and tone. It is for this reason that Gnomish is considered among the hardest languages to master. 
Gnomish is written in the Dwarven script with the runes often modified to contain a separate meaning when removed or added strokes are put together in marked locations.
