Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
The word iunix could not be parsed. Trying a normal dictionary lookup:
jūnix, or uncontr. jŭvĕnix, īcis, f. [juvenix], a young cow, a calf, heifer: tot tibi cum in flammas junicum omenta liquescant, Pers. 2, 47.
In the form juvenix, of a maiden (cf.: δάμαλις, juvenca): quam mox horsum ad stabulum juvenix recipiat se pabulo, Plaut. Mil. 2, 3, 38 Ritschl. dub. (MSS. juvenis).
