Select the sentence containing the homonym of the highlighted word: The fanon…

Concept: A homonym is a word that carries the same form as another word while its meaning and its origin are completely unrelated. The shared form may be the written one (a homograph), the spoken one (a homophone), or both, and in exam usage 'homonym' is the umbrella term that covers them. Finding a homonym therefore means finding that shared form used in a different sense, not another use of the sense already in front of you.

Application: In the highlighted sentence, 'fanon' names an ecclesiastical vestment, the striped silk shoulder-cape worn by the Pope at a solemn Mass. The sense to be matched against is therefore 'papal vestment', so each sentence has to be read for the sense that its own use of the form carries.

• 'The theologian lectured on the fanon's origin in Rome' uses the vestment, discussed as an object of church history.

• 'The tailor stitched the edge of the fanon carefully' uses the vestment again, handled as a piece of cloth.

• 'The cardinal wore the fanon over his chasuble' uses the vestment again, named as an article of clothing put on over other vesture; in strict Roman usage the fanon belongs to the Pope alone, but the sense of the word is unchanged.

• 'The critic analyzed Fanon's theory of postcolonial identity' uses no vestment at all, but the surname of Frantz Fanon (1925-1961), the Martinique-born psychiatrist who wrote The Wretched of the Earth.

Result: three of the sentences reuse the vestment sense, so in them 'fanon' is simply the same word appearing again. Only in 'The critic analyzed Fanon's theory of postcolonial identity' does the identical form carry an entirely unrelated meaning, so that is the sentence containing the homonym.

Cross-check: the two uses share their written form letter for letter, differing only in the capital that marks a personal name, while their meanings and origins are wholly unrelated. The vestment word reaches English through Old French from a Frankish word for cloth, and the other is a French surname. That shared written form carrying an unrelated meaning is what the question tests; how each is stressed in speech does not change it, because the identity here is the identity of the written word.
