Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
intĕr-ĭbĭ (interibei, Sen. con. de Bac. C. 1 R. 196), adv., in the meantime, for interea, interim (ante- and post-class.), Plaut. As. 5, 2, 41; id. Capt. 5, 1, 31; 33; id. Mil. 2, 1, 26; id. Poen. 3, 3, 3; id. Rud. 4, 6, 20; id. Pers. 1, 3, 85; App. Mag. p. 320, 29 (but in Gell. 3, 7, 17, the correct read. is interim).
