Morphology

trend + line

The noun–noun composition 'trend' (general direction) + 'line' (a drawn line) directly denotes a line that shows a trend on a graph, so the overall meaning is immediately derivable from the parts. This is a common, cross-linguistically transparent conceptual combination (e.g. Spanish 'línea de tendencia'), so a B1 learner who knows both constituents would understand it.

Etymology

The noun trend line comes from drawing a line through many small data points on a graph to show the general trend. So, it means the 'overall direction' or 'pattern' of the data.
