Morphology

line + of + sight

The noun phrase combines 'line' (a straight mark or path) with 'sight' (what is visible) via the standard 'X of Y' compositional pattern, so its meaning as an imaginary straight line from the eye to an object is directly derivable from the parts. This construction is common across languages and follows predictable semantics, so a B1 learner who knows the constituents should understand it.

Etymology

Line of sight: The phrase line of sight comes from the simple image of a straight line from your eye to something you want to 'see'. If anything blocks that sight, it blocks your view, so line of sight means the clear path between you and the object.
