The phrase that is translated as “there is no fear in love” in English has been translated in Huautla Mazatec as “he who really loves forgets to be afraid.” “The concepts of love and fear must be expressed by verbs, not nouns, and hence an actor must be expressed. Furthermore, the relationship indicated by the English ‘in’ must be radically altered, for though in can express the relationship of objects to each other in Huautla Mazatec, it does not show the relationship of events, as it does in English.” (Source: Nida 1964, p. 196).
