Morphology

isarithm = iso + arithm (semi-transparent) = iso + arithm

The prefix 'iso-' meaning 'equal' is clear, but 'arithm' is less commonly recognized as 'related to numbers', making the term semi-transparent.

Etymology

The word isarithm comes from the Greek parts iso- meaning 'equal' and arithm meaning 'number', the same root you see in arithmetic. So an isarithm is a line on a map that joins places with the same number, such as the same temperature or elevation.
