Spelling and Odd One Out

YUGOSLAVIA is the correct spelling of this former European country. Options A and B incorrectly omit or transpose letters (YUGSLAVIA, UGOSLAVIA), while option D adds an extra O (UGOOSLVIA).

BURUNDI is the correct spelling of this East African country. Options A, B, and D introduce spelling errors with incorrect consonant substitutions (BRANDI, BRUNDI, BURONDI).

Catechism is the correct spelling for a book or instruction manual explaining religious doctrine through questions and answers. The word comes from Greek 'katechismos' with emphasis on the first 'a' after 'c'. Options B, C, and D all misspell this with incorrect vowel placements.

The German word for 'violet' is 'violett' (with double t at the end). 'Violette' is the French equivalent, 'voilet' is a misspelling, and 'violet' in German usually refers to the flower color rather than the standard purple shade.

Parliament is the correct spelling, from French 'parlement'. Common misspellings often replace 'ia' with 'ae' or misspell the middle vowels. Remember the pattern: par-lia-ment.

This linguistic curiosity is true: the word 'queue' is pronounced /kjuː/. When you remove the last four letters ('euee'), you're left with 'q', which is also pronounced /kjuː/. This makes 'queue' a unique example of English orthography where most letters are silent.

Copper, Zinc, Aluminium, and Iron are all pure chemical elements. Brass is an alloy made of copper and zinc, not a pure element. This makes it the odd one out.

Marigold, Rose, Lily, and Lotus are all flowers. Apple is a fruit (the edible part of the plant), not a flower. This makes it different from the others.

January, May, July, and August are all months with 31 days. November has only 30 days, making it the odd one out based on the number of days.

Pistol, Gun, Rifle, and Cannon are all firearms that discharge projectiles. Sword is a bladed weapon that does not use explosive propulsion. This makes it the odd one out.
