What the lexicon says. נֶפֶשׁ (nephesh) is defined as "soul, self, life, creature, person, appetite, mind, living being, desire, emotion, passion", and the first sense given is "that which breathes, the breathing substance or being, soul, the inner being of man". The sense list runs on through "the man himself, self, person or individual", "seat of the appetites", "seat of emotions and passions" (TBESH, from the abridged Brown-Driver-Briggs).
What the text does with it. In Genesis the word is the end of the sentence, not the middle: "and man became a living soul" (Genesis 2:7, ASV); "the man became a living being" (Genesis 2:7, BSB). The tagged text there reads H5315K, a sense the lexicon glosses "a creature". In the Psalms it is what a person addresses when talking to themselves: "Why art thou cast down, O my soul? And [why] art thou disquieted within me?" (Psalm 42:5, ASV, the brackets are the ASV's own, marking words supplied by the translators), where the tagged word is H5315G.
⚠️
The number is split eight ways. The lexicon divides H5315 into eight lettered senses. The one glossed "soul" (H5315G) is in 230 verses; all eight together are in 691. Reporting 691 as the count for "soul" would be wrong, and so would reporting 230 as the count for the word.
