verb (dots, dotting, dotted)[with object]
Old English dott 'head of a boil'. The word is recorded only once in Old English, then not until the late 16th century, when it is found in the sense 'a small lump or clot', perhaps influenced by Dutch dot 'a knot'. The sense 'small mark or spot' dates from the mid 17th century
