Talk:rudder

Is this the only word in which Middle English -ther became -(d)der? There are of course several words where the opposite happened (father, gather, mother, slither, tether, weather, whither). There are also some in which the original d was preserved (adder, bladder, fodder, ladder, udder). But I'm not aware of another word with a change in this direction. If true, it might be included in the etymology. -- Online Etymology Dictionary only compares "burden" and "murder", but these are evidently different because there's a preceding "r" (and in "murder" perhaps also Old French influence). So this may corroborate that it's the only such word. 88.64.225.53 06:32, 3 January 2024 (UTC)
