Spellings

The correct spelling is 'ebullient' meaning enthusiastic or excited. The other options are all misspelled: 'ebuliant', 'ebulient', and 'ebulliant' are incorrect variants. The correct spelling follows standard English rules with 'll' after 'bu'.

The correct spelling uses double 'c' and double 'm' in 'accommodate'. Many people mistakenly drop one of the consonants, but both letters appear twice.

The correct spelling is 'achieve' with 'ie' after 'ch', not 'ei'. This follows the common pattern where 'i' comes before 'e' in many words.

The correct spelling is 'assassination' with four 's' letters - double 's' appears twice. The root word 'assassinate' already has the double 's' pattern.

'Balloon' is correctly spelled with double 'l' and double 'o'. The double letters indicate the round, swelling shape that gives the word its meaning.

'Battalion' is correctly spelled with double 't' but single 'l' and 'i'. The pattern is 'battal-' (double t) followed by '-ion'.

'Benefit' is spelled with single 'e', 'n', 'i', and 't' - no double letters. Adding extra letters is a common error.

The correct spelling is 'calendar' with 'ar' in the middle syllable, not 'er' or 're'. Many incorrectly use the 'ender' pattern from related words.

'Category' is spelled with 'e' as the second vowel ('cat-e-gory') and ends with 'y'. The 'a' in the first syllable and 'ory' ending can be confusing.

'Ceiling' is correctly spelled with 'ei' after 'c' (remember 'i before e except after c'), and 'ing' at the end. Many mistakenly use 'e' alone or double letters.

The correct spelling is 'cemetery' with three 'e's and no 'a'. This is a famous exception to spelling patterns - all vowels are 'e'.

The correct spelling is 'innocuous' (meaning harmless or inoffensive), not 'inocuous'. The other words are spelled correctly: intransigent (uncompromising), incognito (concealing identity), and illicit (forbidden by law). This tests knowledge of Latin-derived spelling patterns.

The correct spelling is 'deterrent' (something that discourages), not 'detterent'. The other words are spelled correctly: preference, lettering, and betterment all follow standard English spelling patterns. This tests the ability to identify misspelled words among correctly spelled ones.

The correct spelling is 'mission', not 'mision'. The word is missing the first 's'. The other words are spelled correctly: cushion, fusion, and fashion all contain the correct letter patterns. This tests attention to detail in identifying spelling errors.

The correct spelling is 'argument.' In English, when adding the suffix '-ment' to 'argue,' the silent 'e' is dropped, following standard spelling rules. 'Arguement' is a common misspelling that incorrectly retains the 'e'.
