Pulmonalis or Pulmonaris? It's Elementarius, My Dear Watson

Area of Science:

• Anatomical terminology
• Linguistics
• Phonology

Background:

• The adjectival suffixes -alis and -aris are prevalent in anatomical nomenclature.
• Current usage presents numerous exceptions, particularly concerning the substitution of -aris for -alis after an -l-.

Purpose of the Study:

• To empirically investigate the usage of -alis and -aris suffixes in anatomical terminology.
• To develop refined phonological rules to minimize exceptions in anatomical adjective formation.
• To propose standardized terminology based on historical linguistic analysis.

Main Methods:

• Empirical analysis of 985 adjectives from Terminologia Anatomica (2nd ed.) and Terminologia Histologica.
• Development of phonological rules based on observed patterns, including dissimilation effects.
• Review of Latin linguistic precedents and modern language derivatives.

Main Results:

• A tripartite rule (-alis as default, -aris after -l-, with exceptions for intervening -r-) was formulated.
• This rule reduces exceptions to less than 10%, further decreasing to under 6% with distance limitation.
• Specific term recommendations (e.g., pulmonarius, elementarius) are proposed to replace existing forms.

Conclusions:

• The proposed phonological rules offer a more consistent and exception-reduced system for anatomical nomenclature.
• Standardizing suffixes like -alis and -aris enhances clarity and precision in anatomical descriptions.
• The study recommends specific Latin terms for adoption into anatomical vocabulary.
