Morphology

margin + of + error

The meaning 'an allowed or calculated degree of error' is directly derivable from combining 'margin' (an allowance or leeway) with 'error' (a mistake), with 'of' serving as a simple linker; a learner who knows the constituent words can infer the phrase. The noun + of + noun compositional pattern is common across languages (e.g., Spanish 'margen de error', French 'marge d'erreur'), so the expression is readily predictable and transparent to B1 learners.

Etymology

Margin of error comes from the image of a small margin, a border left for possible error or small mistakes, like leaving a little space around a number so a small mistake does not change the result. That's why it means the 'allowed' amount something can be wrong and still be acceptable.
