Etymology
the verb 'soothe' originates from the old english 'sothian', which meant 'to prove to be true'. this is connected to the old english adjective 'soth', meaning 'true, genuine'. both trace back to the proto-germanic 'santhaz', meaning 'true', which itself has a proto-indo-european root 'es-', meaning 'to be', the ultimate source of words related to existence and truth. the semantic journey from 'verifying truth' to 'calming' is intriguing; it likely passed through an intermediate sense of 'to assent to someone as true' or 'to humor by agreeing', which then softened into the meaning of pacifying or comforting someone by assenting to or validating their feelings.
Analysis
the word is a simplex form. it is derived from the old english verb 'sothian', meaning 'to prove the truth of, bear witness to'. the modern sense evolved through the concept of 'assuaging by asserting what is true'.
