plotted

The word 'plotted' is the inflected past form of the verb 'plot'. The noun 'plot', with its core meanings of a small area of land and a secret plan, entered English in the late Old English period with an obscure origin, though it is likely Germanic. The semantic connection between a measured piece of ground and a secret plan likely stems from the concept of a chart or map (a measured representation) which is used to devise a scheme. The verb 'to plot' emerged from these noun senses, and the regular inflection '-ed' is added to indicate past action, following a standard Germanic pattern for forming past tense.

Structure: plot + t + ed - plot: From Middle English 'plot', meaning a small piece of ground or a plan. Origin is uncertain, possibly from Old English. - t: A graphic extension of the root 'plot' to form the past tense/past participle stem. - ed: An inflectional suffix (Old English -ed, -od, -ad) used to form the past tense and past participle of regular verbs.
