Spellings

Concession is the correct spelling. It has double 'c' but single 's'. The word comes from Latin 'concessio'. Distractors incorrectly place double letters or swap vowels.

Dependence is the correct spelling. The noun form of 'depend' ends with '-ence' (not '-ance'). Distractors incorrectly use 'a' or garble the middle consonants.

Supplementary is the correct spelling. The first part is 'supplement' (with one 'l' and double 'm'), and the suffix is '-ary' (not '-ory' or '-asy'). Distractors garble consonants or use wrong suffix.

 The correct spelling is sovereignity.

Commission is the correct spelling. It has double 'm' and single 's' (unlike 'commit' which has single 'm'). Many confuse this with similar-looking words. Distractors use wrong consonant doubling.

Illustrious is the correct spelling. The word means distinguished or celebrated. The double 'l' is followed by 'u' (not 'e'), and it ends with '-ious' (not '-eous' or '-ron'). Distractors garble vowels and consonants.

Cemetery is the correct spelling. Despite ending in '-ery', the vowel sound is 'e' (not 'a'). This is a common exception to the rule. Distractors incorrectly use 'a' or garble consonants.

Commensurate is the correct spelling. It means 'corresponding in size or degree'. The word has double 'm', single 'n', and ends with '-urate'. Distractors garble the consonant order or use wrong vowels.

Overlapped is the correct spelling. The past tense of 'overlap' is formed by adding '-ed' to the base verb. Distractors incorrectly drop the 'p' or garble the middle consonants.

Sacrilegious is the correct spelling. This often-misspelled word means 'violating something sacred'. Note it's 'sacrilegious' (with 'l' after 'i'), NOT 'sacreligious' (which would incorrectly add 'h' to reference 'religion'). Distractors confuse it with 'religious' or garble letters.

Recommend is the correct spelling. It has single 'c' and double 'm' (opposite of what many expect). Distractors incorrectly use double 'c' or single 'm'. This is a very common misspelling.

Aerodrome is the correct spelling. This word refers to an airfield or airport. It follows the pattern 'aero-' + 'drome' (meaning 'course' or 'running'). Distractors garble the 'o' and 'e' order or add extra letters.

Lackadaisical is the correct spelling - it means lacking enthusiasm or determination. The key pattern is the root 'lack' + 'adaisical' with no extra letters inserted.

Cancellation doubles the L and drops the 'e' before adding '-tion'. The pattern follows cancel → cancellation (not cencellation or cancelation).

Allottee (meaning someone who receives an allotment) follows the pattern of allot → allottee with double 't' and double 'e'. Key is the root 'allot' + '-ee' suffix.
