guy, slave, manservant, fellow
奴 centers on a person in a subordinate or low-status role: a servant, slave, or a rough fellow. The meanings range from a derogatory 'guy' to a bonded manservant, all tied to the idea of a lowly person.
奴 combines 女 (woman) and 又 (hand), suggesting a hand seizing a woman, which historically implied a captive or slave. The modern form retains this component structure.
A woman 女 is held by a hand 又, like a servant or slave under someone's control. This lowly position also gives the rough 'guy' sense.
For ド, imagine a lowly servant carrying a heavy door: door -> ド, and the servant struggles under it.
