📚 Study Notes – Rules for Spelling
(Target audience: IEO / English Olympiad / Competitive Exams)
“The language is a set of rules, but the rules are a set of patterns.” – G. H. Hardy
1. Why These Rules Matter
- Accuracy → Correct spelling is a prerequisite for high‑level vocabulary mastery.
- Pattern Recognition → Competitive exams (IEO, JEE‑B, GRE, SAT, etc.) often test the ability to spot spelling patterns in unfamiliar words.
- Morphological Insight → Knowing how words are built helps you deduce spelling of derived forms and unfamiliar terms.
2. Core Spelling Rules (with Derivations)
| # | Rule | Derivation / Pattern | Example |
|---|---|---|---|
| 1 | “I before E except after C” | 1. Vowel pair ie → /iː/ or /aɪ/.2. If preceded by c, use ei. |
believe, receive |
| 2 | Consonant Doubling | When a one‑syllable word ends in a short vowel + consonant, double the consonant before adding a suffix beginning with a vowel. | run → running, big → bigger |
| 3 | Silent ‘e’ | The terminal e is silent but keeps the preceding vowel long. |
rate, bake |
| 4 | –tion / –sion | Words ending in -tion usually come from Latin /ti/ → tion. -sion is used when the root ends in -si- or -si-. |
motion, decision |
| 5 | –ph vs –f | ph keeps the /f/ sound. It appears in Greek‑derived words. |
telephone, graph |
| 6 | –gh | Pronounced /f/ in enough, cough; /g/ in night, give, and silent in many others. | cough, night |
| 7 | –ck vs –k | ck is used when the preceding vowel is short and the word ends in a consonant. k is used otherwise. |
back, bark |
| 8 | –ch / –tch | ch (pronounced /tʃ/) in words of Old English origin; tch for keeping the /t/ + /ch/ sound before a vowel. |
match, catch |
| 9 | –y → –ies | When a word ends in a single consonant preceded by a short vowel, replace y with ies in the plural. |
city → cities |
| 10 | –ian / –ean | Both suffixes mean belonging to or originating from, but spelling depends on the root: • -ean after words ending in -e, -el, -ir. • -ian after words ending in -y, -i, -e + t. |
Canadian, American, Australian |
| 11 | –tion vs –sion | Derive from Latin: -tion comes from -tio; -sion from -siōnem. Use the variant that matches the root. |
relation, decision |
| 12 | –en vs –in | -en used after consonants d, t, l, g, n; -in after most other consonants. |
baked → baked, lifted → lifted |
| 13 | –th (soft /θ/ vs hard /ð/)** | th is silent in both, pronounced /θ/ in bath, /ð/ in breathe. No spelling rule—learn by exposure. |
thick, bath |
| 14 | –ight vs –ight | ight is always /aɪt/. |
fight, light |
| 15 | Homophones | Words that sound identical but differ in spelling and meaning. | their / there / they’re |
