Very useful and versatile word.
Indicare (to show, to indicate or to point out) and indire (to hold [a referendum], to organize [a hearing]) are two totally separate words who HAPPEN to have the EXACT SAME SPELLING for their conjugation in the PRESENT TENSE due to "indire" being conjugated like the irregular "dire":
I guess you will know by context which is which. I did not see any other tense with the same spelling. Hope that helps. Interesting question.
