Definition decision workflow
1. Identify the role
Check whether "nadir" is acting as name, noun, verb in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option
Compare it with "base" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
3. Confirm with context
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Final meaning check
Before publishing a sentence with "nadir", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Etymology
Etymology 1
From Medieval Latin nadir, from Arabic نَظِير السَّمْت (naẓīr as-samt), composed of نَظِير (naẓīr, “counterpart, corresponding to”) and السَّمْت (as-samt, “the zenith”).
Etymology 2
Unknown. It has been suggested that it is from Arabic نَزِير (nazīr, “rare, trivial”), but if it is Arabic, perhaps more likely would be نَذِير (naḏīr, “auspicious, boding well (?)”). Represents the word 'rare' in Hebrew.
