Morphology
musculus + transversalis + abdominis
The term is a compositional Latin anatomical name: musculus (muscle) + transversalis (transverse) + abdominis (of the abdomen), so its meaning 'transverse abdominal muscle' is directly derivable from the parts. Anatomical Latin is systematically built and similar across languages, so a learner who knows the constituent elements would readily infer the overall meaning.
Etymology
Musculus transversalis abdominis comes from old Latin words: musculus meant 'little mouse' because a moving muscle looked like a small mouse under the skin, transversalis meant 'across', and abdominis meant 'belly'. So the name gives the picture of a thin muscle running across your belly, which helps you remember it is the deep abdominal muscle.
