Silent Letters

know write climb listen

Double Letters

One or two? Hard to remember

necessary accommodate embarrass occurred

Unstressed Vowels

Vowels that all sound like “uh”

separate definitely calendar gramar

Homophones

Sound alike, spelled differently

their / there / they’re its / it’s affect / effect

Borrowed Words

Kept their foreign spelling

restaurant rhythm colonel rendezvous

Rule Breakers

necessary

Double Letters

Common mistake: ~~neccessary~~

💡 One collar (c), two sleeves (ss).

Spelling Tips That Actually Work

✂️

Break words into syllables

Long words become manageable chunks. “Definitely” = def-i-nite-ly. “Wednesday” = Wed-nes-day.

🗣️

Say it how it’s spelled

Exaggerate pronunciation to remember tricky letters. Say “Feb-RU-ary” and “choc-O-late” even if it sounds funny.

🧠

Use mnemonics

Memory tricks make spelling stick. “Necessary has one collar (c) and two sleeves (ss).” “There’s A RAT in sepARAte.”

🔍

Spot prefixes and suffixes

Recognizing word parts helps: un-, re-, -tion, -ment. “Misspell” = mis + spell (that’s why it has two S’s).

✍️

Write it out repeatedly

Muscle memory works. Write the word 5-10 times while saying it. Your hand will remember.

📝

Keep a personal word list

Track the words YOU miss most often. Review them weekly. Everyone has their own trouble words.
