Surface Forms
Morphology
multifidus = multi + fidus
Although the form reflects the same Latin elements, the noun is a specialized anatomical term whose referent is not directly inferable for most learners.
Etymology
Multifidus comes from the Latin parts multi- 'many' and -fidus 'split', and it names a deep back muscle made of many small parts along the spine. So the word helps you remember that this muscle is formed of many pieces that work together to keep the spine steady.
