Spellings

Compassion is the correct spelling, using double 's' (com-pas-sion). The root 'pass' retains its double 's'. Common errors include dropping one 's' or misspelling the vowels. The prefix 'com-' combines with 'passion' - the double 's' is essential.

Expiation is the correct spelling (ex-pi-a-tion). It means the act of making amends or atoning for guilt. The word comes from Latin 'expiare'. Note the single 'p' followed by 'ation'. Common errors include dropping the 'i' or confusing consonant placement.

Abbreviation is the correct spelling, using double 'b' (ab-bre-vi-a-tion). The root 'brev' (short) combines with 'ab-' and '-ation'. Remember that both 'b's are retained in the prefix-root combination. Common errors include dropping one 'b' or misspelling vowels.

Addition is the correct spelling, using double 'd' (ad-di-tion). The root 'add' retains its double 'd' when '-ion' is added. Common misspellings often drop one 'd' or confuse the vowel placement. Remember that 'add' + 'ition' = addition.

The correct spelling is 'Evacuation' with a 'c' after 'e' and 'tion' at the end. Remember that words starting with 'e' usually keep the 'e' before 'va' (evacuate, evaluation). The common mistake 'Evacuetion' incorrectly substitutes 'ue' for 'ua'.

The correct spelling is 'Aggravation' with double 'g' and single 'v'. The pattern comes from 'aggravate' - keep the double 'g' when adding the suffix. Common errors include dropping a 'g' or adding extra 'r'.

The correct spelling is 'Discrimination' with 'i' after 'D' and 'mination' ending. This follows the pattern of 'discriminate' replacing 'ate' with 'ion'. Don't confuse it with similar-sounding words that might have 'e' in the middle.

The correct spelling is 'Desecration' meaning to violate something sacred. The pattern is 'de-' + 'secrate' + '-ion', keeping the 'e' after 's'. Common errors confuse the vowel placement or add extra 'r'.

The correct spelling is 'Dejection' with 'j' not 'ct' or 'ck'. The word comes from 'deject' and follows standard spelling rules. Remember that '-jection' words (inject, project, reject) all use 'j'.

The correct spelling is 'Erosion' with single 'r' and single 's'. It comes from 'erode' + '-ion'. The common mistake 'Erosion' incorrectly doubles the 'r' - remember that 'e-ro-de' keeps the single 'r' pattern.

The correct spelling is 'Fusion' with single 's' in the middle, not double. Think of similar words like 'confusion' or 'diffusion' - they follow the same single 's' pattern. The incorrect 'Fussion' incorrectly doubles the consonant.

The correct spelling is 'Obsession' with 'ss' but single 's' in the middle. This is a tricky one - the first syllable has single 's', while the second has double 'ss'. Pattern: ob-SES-sion, not ob-SESS-ion.

The correct spelling is 'Procession' with single 's' after 'Pro' and double 'ss' before 'ion'. The pattern comes from 'process' - when adding '-ion', you keep the single 's' but double it before the suffix ending. Don't confuse with 'prossession' which doubles incorrectly.

The correct spelling is 'Elision' with 'E' at start, single 'l', and 'sion' ending. This linguistic term refers to omitting sounds in speech. The key is remembering it starts with 'E' not 'A', and has single 'l' and 's' in the middle.

The correct spelling is 'Incubation' with single 'n' and 'b', and 'tion' ending. This follows the pattern of 'incubate' replacing 'te' with 'tion'. Common mistakes include doubling consonants or changing vowels.
