Obtain, which was adopted into English in the 15th century, comes to us via Anglo-French from the Latin obtinēre, meaning "to hold on to, possess." Obtinēre was itself formed by the combination of ob-, meaning "in the way," and the verb tenēre, meaning "to hold." In its earliest uses, obtain often implied a conquest or a successful victory in battle, but it is now used for any attainment through planned action or effort. The verb tenēre has incontestably prevailed in the English language, providing us with such common words as abstain, contain, detain, sustain, and, perhaps less obviously, the adjectives tenable and tenacious.
