remark: [17] Remark originated in French as an intensified version of marquer, in the sense ‘observe, notice’ (French had acquired marquer from the same Germanic source as produced English mark). The sense ‘say something’ emerged from the notion of ‘making a verbal observation’. The derived remarkable [17] soon developed the sense ‘extraordinary’ from its original ‘worthy of being noticed’.
