I’ve been struggling with this little problem for a while now, so I thought I’d share it to see what you guys think.
I have displayed the definitions of the two words in question below.
Oxford Dictionary
Shameful: worthy of or causing shame or disgrace
Shameless: (of a person or their conduct) characterized by or showing a lack of shame
So first, let's get some clarity. If someone is described as “rude,” it usually means that they have a rude behaviour. Similarly, if someone is described as “optimistic,” it means that they have an optimistic behaviour. Sounds reasonable, right?
Shameless vs Shameful
If someone was to be described as “shameless,” this would imply that they have no shame but ought to be ashamed of themselves. (i.e. showing a "lack" of shame)
Curiously, taking the word’s opposite, “shameful,” means much the same thing: Someone described as “shameful” would imply that this person ought to be ashamed of themselves, or were behaving in a manner worthy of shame. (e.g. "That shameful man!")
The Conflicting (Nuanced & Contextual) Meanings of "Shameful"
Additionally, the word "shameful" seems to be variable. Take the phrase “Frederick nodded shamefully,” for instance.
This phrase could imply that Frederick was feeling ashamed of himself, as opposed to implying that he was nodding in a way worthy of shame.
Interestingly, a small change to the wording can completely flip the meaning: “Frederick nodded in a shameful way” might imply that Frederick nodded in a manner that he ought to have been ashamed of.
Summing it Up
Could someone please help clarify the real connection between the words "shameless" and "shameful"? Why do these opposite words actually cross-over in so many areas? Have the implicit definitions of these words changed/converged over time?
Additionally, why does the meaning of “shameful” seem to change depending on the tone of the surrounding text?
I'm talking about the nuances and contextual differences between the words here, not just their basic definitions.
It would be great to hear some of your thoughts/ideas.
Thanks in advance!
