masc nom sg of samatta (pp)
Analysis. sam- (together, completely) + atta (past participle of attati, 'to attain'), hence 'completely attained' or 'brought together to completion'.
Etymology. sam + √att (to attain, fit, join). The prefix sam- ('together, completely', cognate with Latin con- and English same) combines with the root att- (Indo-European *ad-, 'to fit'; related to English adapt). The spatial sense of sam- (things brought into one whole) becomes the abstract notion of perfection and completeness.
