Spelling Correction

English spelling is irregular but not random. Four patterns cover most of what the paper asks.

1. Double letters. accommodation (two c, two m), embarrass (two r, two s), occurrence (two c, two r), committee (two m, two t, two e), possession (four s in pairs). Against them stand the single-letter traps: harass (one r), necessary (one c, two s), until (one l).
2. Endings. -able after a complete word (comfort → comfortable), -ible after a stem that is not a word (poss → possible). Only three words end in -ceed (proceed, exceed, succeed), one ends in -sede (supersede), and the rest take -cede (precede, recede, concede).
3. The ie / ei rule. i before e, except after c: believe, achieve, relieve — but receive, deceive, ceiling.
4. Doubling before a suffix. A short stressed vowel doubles the consonant: occur → occurring, refer → referred, begin → beginning; but benefit → benefited and offer → offered, because the stress is not on the last syllable.

The single most common mistake is spelling by pronunciation, which is exactly what a Marathi-medium reader is trained to do, since Devanagari is written as it is spoken: "goverment" for government, "enviornment" for environment, "definately" for definite, "seperate" for separate.

How to check: say the word syllable by syllable in full — gov-ern-ment, en-vi-ron-ment, sep-a-rate — and remember that definite contains finite and separate contains a rat.

accommodation, embarrass, occurrence, committee double up; harass, necessary, until do not · -able after a whole word, -ible after a stem · only proceed, exceed, succeed take -ceed; supersede takes -sede · i before e except after c · stress on the last syllable doubles the consonant

Which spelling is correct: acommodation / accomodation / accommodation / accomadation? → accommodation. Sanity check: the word is built from "ac" plus "com" plus "modation", and each of those parts keeps its own consonant, giving two c and two m. A memory hook that survives exam pressure: a good lodging offers two cots and two mattresses.
