Regional Synonyms
The dictionary's definitions typically present regional synonyms for words. For instance, the entry for 'tiger' (虎, hu) illustrates this method by detailing various regional names for the animal.
The 'Tiger' Entry Example
The entry for 'tiger' (虎, hu) demonstrates the dictionary's approach: "In the regions of Chen-Wei Song-Chu [Central China], some call it lifu; in the regions of Yangtze-Huai Nan-Chu [Southern China], they call it li'er, and some call it wutu. From the Pass, east- and west-ward [Eastern and Western China], some call it also bodu." This highlights significant lexical variation across geographical areas.
Linguistic Reconstruction
Comparative linguists have leveraged the dialectal data within the Fangyan to reconstruct the pronunciation of Eastern Han Chinese. This historical stage is crucial for understanding the evolution from Old Chinese to Middle Chinese, providing vital insights into the diachronic development of the language.
