Morphology

Isatis + tinctoria

This is a scientific binomial composed of a genus name ('Isatis') and a species epithet ('tinctoria') whose element 'tinct-' relates to dyeing; together they denote the dye-producing plant (woad). If a learner knows the constituent elements (and their dye-related senses), the overall meaning is directly compositional and predictable rather than idiomatic.

Etymology

Isatis tinctoria takes its name from the word tinctoria, which comes from Latin and is linked to 'dyeing'. People once used the plant's leaves to make a strong blue dye called 'woad', so the name shows it was a plant used for making dye.
