free: released from slavery, obligation, or bondage, and so no longer owned or bound
The word describes a person or creature that is free: no longer owned, bound, or in service. Most of its uses come from the laws about servants, where a Hebrew servant who has worked six years, or who has been injured by his master, is sent out "free."
From that legal core the word stretches naturally. A soldier can be made "free in Israel," meaning released from the king's service and dues. The wild donkey is "free," running loose where no one has harnessed it. And in death even a servant is "free" from his master, released from every burden of life at once.
The act of freeing has its own separate word, the "liberty" (דְּרוֹר) that is proclaimed; this word names the resulting status, the freed person. In Job and especially in Psalm 88 the word is used of the dead, where the freedom is less relief than being cut off from the land of the living.
Nuances
What "free" means in the phrase "free among the dead" in Psalm 88:5.
- majorityIt means "free" in a bitter sense: the speaker lies among the slain like a dead man, released from life but for that very reason cut off from God's care and no longer remembered.; BDB, s.v. חׇפְשִׁי
- minorityThe word here reflects an older sense tied to the realm of the dead, attested in a term for the underworld in Ugaritic texts, giving something closer to "set apart among the dead" than "free."; HALOT, s.v. חׇפְשִׁי
