naked or nude ?
There is no real difference - except maybe philosophically.
"Naked" to me involves "something more" than the mere absence of clothing. It's the "physical and emotional behavior" of the unclad person; be it be vulnerability or strength.
Someone at a nudist resort can be completely undressed; yet be self-conscious and reserved about their appearance, choosing a more "static" positioning vis--vis other people.
Contrast this with the "active" nudist, who is walking, swimming and socializing openly naked. Hence "naked" vs "nude."
My wife once mused that she had never felt as "naked" as the time she decided to go paddle-boarding at the resort lake. That's because even though she had been nude sitting by the pool or lake (statically); she had never been as openly naked, balancing and standing on the board, while (dynamically) paddle-boarding her way back and forth, as other nudists observed. In her case the "nakedness" came from both a sense of vulnerability ("everyone can see me completely naked!") and strength ("I love that I can be comfortable doing this!") I think her example provided a good illustration of the contrast between the two terms.
Vulnerability is probably the strongest distinction. Some people describe not wearing a seatbelt in a moving car as a feeling of nakedness while I've even noticed feeling it when mask restrictions are relaxed (only for an instant, LOL).
English certainly is rich in vocabulary with many different words with subtle differences in meaning. To me, English doesn't just borrow words from other languages, it follow them up dark alleys, assaults them, and takes what it wants!
Most likely, just a pronunciation: the second, which is 'nude' - 'naked', and the first, 'naked' - just 'bare', i.e. more simplified word. But that's just my opinion, of course... Moreover, the word 'naked' also has such meanings as 'explicit', 'open', 'uncovered' - sometimes they are used as synonyms
