Use only FIVE pairs of words in sentences clearly illustrating their meanings: Blurt / Blert, Aeipathy / Apathy, Defenestration / Dénouement, Vallum / Vellum, Sow / Sough, Sere / Seer, Crepuscular / Crepitation, Uxoricide / Uxorious.

Pairs of words in sentences

Six pairs are given here; only five are required.

Defenestration / Dénouement

The defenestration of Prague in 1618, when officials were thrown from a castle window, helped spark the Thirty Years' War. — In the dénouement of the novel, the long-lost brothers are reunited and every secret is explained. (Defenestration = throwing someone out of a window; dénouement = the final resolution of a plot.)

Vallum / Vellum

South of Hadrian's Wall the Romans dug a vallum, a broad ditch between earth banks. — The old Quran was copied by hand on vellum. (Vallum = a Roman earthwork or rampart; vellum = fine parchment made from calfskin.)

Sow / Sough

Farmers in Punjab sow wheat in November. — We heard the sough of the wind through the pine trees at night. (Sow = plant seed, also a female pig; sough = a soft murmuring or sighing sound of wind.)

Sere / Seer

After two years of drought the fields of Tharparkar lay sere and cracked. — The villagers consulted an old seer who claimed to foretell the future. (Sere = dry and withered; seer = a prophet.)

Crepuscular / Crepitation

Deer are crepuscular animals, most active at dawn and dusk. — The doctor heard crepitation, a fine crackling sound, in the patient's lungs. (Crepuscular = of or active in twilight; crepitation = a crackling sound or sensation.)

Uxoricide / Uxorious

The court convicted him of uxoricide, the murder of his wife. — He was so uxorious that he would not take a single decision without his wife's approval. (Uxoricide = killing one's wife; uxorious = excessively fond of or submissive to one's wife.)

About the other two pairs

"Blurt" (to say something suddenly and without thinking) and "apathy" (lack of interest or feeling) are common words, but "blert" does not appear in standard dictionaries, and "aeipathy" appears only in lists of rare words, glossed as "a continuing passion". Since only five pairs are required, the safest course is to leave these two out rather than guess.

Tip

In a "use in sentences" question the sentence must show the meaning, so add a context clue (a court, a doctor, a drought). Writing a short meaning in brackets after the sentence makes your intention clear to the examiner.
