Her thoughts turned around this question and lighted upon Mansurov-Kurilsky, a talentless man if ever there was one, but not a bad man, all in all, and therefore in every respect a good match for her (1a).

     ♦ ...Отец [Сергея] когда-то был крупный работник, но так никуда и не вылез, мать - домашняя юристка с принципами и запросами, и он сам им под стать (Трифонов 3). ...His [Sergei's] father had once been an outstandingly able man; yet he had never made it to the top; his mother was a nonpracticing lawyer with principles and high standards - and Sergei was similar in nature to both of them (3a).
4. под стать кому [subj-compl with быть (subj: infin); often neg]
