@formation of luT tense

Sometimes, /tRc nouns may look like /luT verbs.

/tRc-formed nounbases show the gender of their doer, and their object has sixth ending, like the janayitR- जनयितृॱ nounbase here —

janayitA rAjarSINAm जनयिता राजर्षीणाम् "he is a progenitor of kingseers", "at least three kingseers will be born in his line"

janayitrI rAjarSINAm जनयित्री राजर्षीणाम् "she is a progenitrix of king-seers"

But the /luT janayitA जनयिता, like all verbs, does not show gender, and its object has second ending —

janayitA rAjarSIn जनयिता राजर्षीन् "he / she will beget kingseers"

More examples —

kR कृ + /luT /tip
→ kR कृ + /tAs + /tip by syatAsIlRl...
→ kar कर् + /tAs + /tip by gbS
→ **kartA' कर्ताऽ "he's gonna do"

han हन् + /luT /tip
→ han हन् + /tAs + /tip by syatAsIlRl...
→ !**hantA' हन्ताऽ "he's gonna kill"
