Morphology
The meaning 'be vigilant / take care' is directly derivable from combining 'watch' (to be watchful) with the particle 'out', which signals outward attention or caution; this follows a common, compositional verb+particle pattern. Because the components and the compositional logic are straightforward and cross-linguistically common, a B1 learner who knows both words would very likely infer the MWE meaning.
Etymology
The phrase watch out comes from the image of someone doing a watch out, looking carefully ahead to see any danger. So it means 'be careful' or 'try to avoid danger'.
