Adjectives in the genitive plural

Features of declensions I and II

For words belonging to the first and second declensions, the main markers of the genitive plural are the endings -orum and -arum. The choice of a specific option is determined by the gender of the term.

The formation process is clearly demonstrated by classical examples of basic definitions:

• Long (longus) naturally transforms into the form longorum.
• Deep (profundus) takes the form profundorum.
• Large (magnus) changes to magnorum.
• Small (parvus) shifts to parvorum.

This principle of formation also fully applies to the superlative degree:

• Smallest (minimus) forms minimorum.
• Largest (maximus) changes to maximorum.

Specifics of declension III and the comparative degree

The third declension requires special attention during study, as it distinguishes various morphological subgroups. For the so-called vowel group of the third declension, the ending -ium is used.

Examples of vowel group form formation:

• Radial (radialis) shifts to radialium.
• Short (brevis) becomes brevium.
• Simple (simplex) takes the form simplicium.

Forms in the comparative degree behave completely differently. Grammatically, they belong to the consonant group of the third declension. The most important distinguishing feature of this group is the use of the short ending -um:

• Superior (superior) turns into superiorum.
• Anterior (anterior) becomes anteriorum.

Practicing term agreement

In medical terminology, modifiers must always strictly agree with nouns. For confident mastery of the material, it is necessary to regularly practice translation using specific anatomical structures.

Key groups of structures for practice:

1. Branches (Rami): requires the ability to agree mastoid, glandular, and intermediate words. Additionally, this includes terminal, main, and accessory branches, as well as organ branches — duodenal and gastric.
2. Foramina (Foramina): the group includes alveolar, acinar, tubular, and mucous formations, as well as papillary, intervertebral, and sacral foramina.
3. Muscles (Musculi) and Ligaments (Ligamenta): for the muscular system, facial, intertransverse, and suboccipital muscles are practiced; for the ligamentous apparatus, auricular, ventral, and yellow tracts.
4. Joints (Articulationes): it is necessary to agree cartilaginous, fibrous, vertebral, and synovial terms.
5. Veins (Venae): an extensive network including atrioventricular, bronchial, pharyngeal, nasal, labial, maxillary, tympanic, occipital, and superficial vessels.
6. Lymph nodes (Nodi lymphoidei): occipital, parotid, facial, lingual, submental, jaw, cervical, pyloric, gastric, splenic, hepatic, mesenteric, and prevesical nodes.
