Morphology

sourceless = source (transparent) = source + less

Literal negative formation meaning 'without a source', straightforward for learners who know 'source' and '-less'.

Etymology

Sourceless is made of the parts source ('origin') and -less ('without'), so it simply means 'having no known origin'. This helps you remember things like a rumor or a light that seems to come from nowhere as 'sourceless'.
