Stretch **zvan- श्वन् /yuvan- /maghavan- (when whimpy), but not before a /taddhita.

**zvan- श्वन् + /TA
→ zun शुन् + A आ by this rule and samprasAraN...
→ !**zunA शुना "with a dog"

**yuvan- युवन् + /Gas
→ yu यु + u उ + n न् + /Gas, where this rule applies only to the v व् because of vibhASAGizyoH >>>
→ yU यू + n न् + /Gas by akassavarN...
→ !**yUnas यूनस् "of the young 'un", "of the heir"

**yuvan- युवन् + /TA
→ !**yUnA यूना "with the heir"

/maghavan- + /Gas
→ magha मघ + u उ + n- न् + /Gas by this rule
→ magho मघो + n न् + as अस् by AdguNaH
→ !**maghonas मघोनस् "of indra इन्द्र"

Why "only when they are whimpy"?

When they are before strong —

**yuvan- युवन् + /su → !**yuvA युवा (like **rAjA राजा)

**yuvan- युवन् + /am → yuvAnam युवानम् (like **rAjAnam राजानम्)

he हे !**yuvan युवन् (like he हे **rAjan' राजन्ऽ)

When they are /pada —

**yuvan- युवन् + /bhis → !**yuvabhis युवभिस् like **rAjabhis राजभिस्

**yuvan- युवन् + **rAjan- राजन् → !**yuvarAja- युवराजॱ "heir apparent"

Why "not before a /taddhita"?

zvan श्वन् + /aN'' → !**zauvanam शौवनम् "canine"

yuvan- युवन् + /aN'' → !**yauvanam यौवनम् "youth"

Why is there no n न् at the end of yuvarAja- युवराजॱ?
