Inops = weak; lacking; destitute
potentem = strong; forceful; mighty
dum = while, as long as, until; provided that; if
vult = be willing; wish
imitari = imitate; follow; reproduce; create
perit = die, pass away; be ruined, be destroyed; go to waste
I can't understand where 'grunde' (profunda) is found in the source text. "Inops potentem" is more likely 'når styrken afsaknes'...etc.
