What does commingled mean?
Commingled is the past tense and past participle of the verb 'to commingle', meaning to blend or mix things together until they form a single mass or collection whose parts are no longer readily separable. The word appears most often in formal, technical, and professional contexts. In finance and law, 'commingled' carries particular weight: when an investment manager or trustee commingles client funds with personal or firm assets, it violates fiduciary duty and can trigger disciplinary action — hence phrases like 'commingled funds' and 'commingled assets'. In environmental contexts, commingled describes mixed recyclable materials collected together before sorting, as in commingled recycling programs. Though it overlaps in meaning with 'mixed', 'blended', and 'mingled', commingled suggests a thorough interpenetration of distinct elements and tends to sound more official or institutional than everyday alternatives.

"The estate's funds were commingled with his personal savings."

"Regulators found that the trustee had commingled client funds with his own accounts."
In finance, keeping money commingled is a serious offense — lawyers and fund managers can lose their licenses for letting clients' cash blend with their own.

Etymology of commingled
Commingled derives from the verb commingle, which English formed in the late sixteenth century from Latin roots: com-, a combining form meaning 'with' or 'together', plus mingere/miscere-related material that also gave English the verb mingle via Middle English mengen, itself borrowed from Old French mengier, from Late Latin minglere. The word thus belongs to the same broad family as mingle and other terms of mixing. Its use intensified in American financial and legal writing during the nineteenth and twentieth centuries, where it became the standard term for improperly or deliberately blended funds.
