Spellings

Feminine is correct.

Theory is correct.

Professor is the correct spelling.

Benevolence is the correct spelling for the quality of being well-meaning or kind. It follows the Latin root bene, meaning well, which helps in remembering the e in the first two syllables. The other options incorrectly use i or a in the middle of the word.

Option (2) is correctly spelt.

Definite is correct.

Pronunciation is correct.

Enthusiasm is the correct spelling for intense and eager enjoyment or interest. It is often misspelled by adding an i before the m or by using an a instead of the initial e. The correct form ends with the suffix asm.

Continuous is the correct spelling for something that happens without pause. The suffix uous is a common ending for adjectives in English, and continuous follows this standard pattern. Other options like B, C, and D are phonetic misspellings or contain extra letters.

Muscular is the correct spelling for an adjective relating to muscles. The suffix ar is used here, which is a common ending for adjectives, though it is sometimes mistaken for er. Options A, B, and D use incorrect vowels or consonants.

Apostrophe is the correct spelling for the punctuation mark used in possessives and contractions. It ends with a single silent e, and common misspellings often involve doubling the final vowel or adding extra consonants like in options A, B, and C.

Characteristic is the correct spelling for a distinguishing feature or quality. It is derived from character and follows a specific pattern of vowels (e followed by i) that is often confused in writing. Options A, C, and D use incorrect vowels in the middle syllables.

Sincerely is the correct spelling for the adverb form of sincere. When adding the suffix ly to a word ending in e, the e is typically retained unless the word ends in le. Options A, B, and D incorrectly modify the spelling of the root word.

Itinerary is the correct spelling for a planned route or journey. It is often misspelled by changing the i in the second syllable or the a in the fourth syllable to other vowels, as seen in options A, B, and C.
