Morphology

isoline = line (semi-transparent) = iso + line + iso

Formed from the combining form 'iso-' meaning 'equal' and 'line'; the construction is systematic in scientific terms but 'iso-' may not be known to an average B1 learner.

Etymology

Isoline comes from the prefix iso- 'equal' and the word line, so it means a line that joins places with the same value on a map, like the same temperature or the same height.
