whole and complete, with nothing lacking or false in it: sound and entire, and of a person, of undivided integrity
At its core this word means simply "whole." Whatever it describes is complete, with nothing missing, nothing added, and nothing false. The same word can therefore stretch across very different settings: wooden frames fitted snugly together, a beloved who is flawless in her lover's eyes, a calm and settled temperament, and above all a person whose life holds together as one honest piece.
That last, moral use is by far the most common, and it carries the most weight. It gathers around the book of Job, where Job is given this word by the narrator and then twice by God himself. It stands beside its regular partner יָשָׁר, "upright," to describe the whole person: an integrity on the inside matched by straight dealing on the outside, reverence for God matched by turning away from evil.
The single hardest occurrence is Genesis 25:27, where Jacob is called by this word even though his story is full of bargaining and deception. Readers have disagreed for centuries over what it means there, and the main proposals are laid out on that verse.
One thread runs through every use: the word points to wholeness, not to flawlessness. A person can be called "whole" in this sense and still be a sinner, as Job himself keeps insisting.
Nuances
What the word means when Jacob is called a man who is tam in Genesis 25:27, since the moral sense it carries elsewhere sits awkwardly with his later scheming.
