opt

The verb 'opt' entered English in the late 19th century, borrowed directly from the French 'opter', meaning "to choose for oneself." The French term originates from the Latin 'optāre', which carried the core senses of "to choose, desire, wish for." This Latin root is itself believed to descend from the Proto-Indo-European base op-, meaning "to choose" or "to take." The word's journey reflects a streamlining of form and meaning, moving from a broader concept of wishing in Latin to the specific, decisive act of making a selection in modern English, often used in formal or contractual contexts.

This is a simplex word, a direct borrowing from French, which itself derived from Latin. It is not productively segmented into smaller, meaningful parts in modern English spelling.
