Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
* ū̆trŭbīdem (ū̆trŏbīdem), adv. [utrubi-dem], on both sides, on each or either side (when the two sides are spoken of): utrosque percognovi utrubidem, Plaut. Truc. 1, 2, 50 (dub.; Speng. utrosque pergnovi probe).
