Pronunciation: [nˌɒt ɛndjˈʊ͡əz] (IPA) 
The correct spelling of the phrase "not endures" is /nɑt ɪnˈdʊrz/ or "not in-duhrs". The first word "not" is spelled as usual, but the second word "endures" has a slight modification. The stress falls on the second syllable, "dures," hence the letter "e" changes to "i" to indicate a short /ʊ/ vowel sound. This is a common spelling rule in English where a stressed syllable with a short vowel sound is followed by an "r" sound.
"Not endures" is a phrase that can be broken down into two separate words to understand its meaning better. "Not" is an adverb used to negate or deny the action or quality of something, expressing the absence or reverse of a particular condition. On the other hand, "endures" is a verb that means to persist or bear up against something difficult, unpleasant, or challenging. It implies the ability to withstand or tolerate adverse circumstances without giving in or succumbing.
Therefore, "not endures" refers to the opposite of enduring or not being able to withstand or tolerate a certain situation, hardship, or discomfort. It signifies a lack of resilience, fortitude, or capacity to persevere through adversity. It implies a disposition towards giving up easily or being unable to cope with challenging conditions.
The phrase "not endures" suggests a potential vulnerability or weakness in a person's resilience, indicating that they may struggle to handle difficulties or endure prolonged periods of discomfort. It can also imply an inability to summon the mental or emotional strength needed to persevere through hardships. Furthermore, this phrase can be used to describe someone who is characterized by their tendency to avoid unpleasant or challenging situations rather than facing and enduring them.
The phrase not endures is not a separate word and therefore does not have an etymology of its own. However, if you are referring to the word endures, its etymology can be traced back to the Latin word indurare, which means harden or make hard. This Latin word is derived from the prefix in- (meaning in or into) and durare (meaning to harden or to last). Over time, endures evolved through Old French and Middle English to its current form, meaning to continue to exist or last.
