Morphology

without + doubt

The phrase literal composition 'without' (lacking/absence) + 'doubt' (uncertainty) yields 'lacking uncertainty' = certainty, so a B1 learner who knows both words can directly derive the meaning. This is a regular compositional pattern in English (and has clear equivalents in many languages), making the expression immediately comprehensible without prior exposure.

Etymology

Without doubt shows the idea of without + doubt: imagine someone removing the doubt (a dark cloud or a question mark) so the view is clear. That's why it means 'certainly'.
