You’ve probably paused over a word and thought, “Why is this so hard to spell?” Well, English spelling breaks its own rules sometimes. And here you’ll learn some simple spelling reminders to help you catch errors before they slip through.
Missing Silent Letters
Silent letters aren’t random. They exist because English kept older spellings even after pronunciation changed.
One perfect example is the word knight. In Old and Middle English, the word was pronounced with a hard ‘K’ sound, but eventually, the letter K became silent. Another example is the word debt, which comes from its Latin root debitum.
Another reason why there are silent letters? To tell words apart (in writing, of course). Let’s take a look at the words write and rite. They sound identical, but actually have different meanings (more on this later!).
In some instances, words with silent letters signal how a word should sound. For instance, a final silent e often tells you the vowel earlier in the word is long, like hope vs. hop.
Take a look at these common silent letter patterns:
- Silent B after m or before t: thumb, comb, subtle
- Silent K before n: know, knee, knight
- Silent G before n: sign, gnome, foreign
- Silent P in some Greek-derived words: psychology, pneumonia
- Silent H at the start of some words: hour, heir, honest
- Silent C in combinations: muscle, scissors
Position of ‘I’ and ‘E’
You’ve heard the rule – Write “i” before “e,” except after “c.” But, guess what? It isn’t always applicable. You should also switch the order when it sounds like an “a,” as in neighbor or weigh.
Remember:
- If it sounds like “ee” → usually ie
- If it follows c and sounds like “ee” → usually ei
- If it doesn’t sound like “ee” → you shoudln’t follow the “i” before “e,” except after “c” rule
Tip: There are common exceptions, such as weird, seize, height, foreign, and caffeine.
Single and Double Letters
English commonly doubles a consonant after a short vowel, so you don’t accidentally change the vowel’s pronunciation—for example, rabbit and dinner.
Other reasons for doubling consonants for some words? The 1-1-1 rule (one syllable, one short vowel, and one consonant) and keeping the original spelling structure of borrowed words from other languages.
Here are some common mistakes:
- embarasment → embarrassment
- definate → definite
- accomodate → accommodate
- occassion → occasion
- adress → address
- untill → until
- succesful → successful
- begining → beginning
- recomend → recommend
- diferent → different
- aparently → apparently
- tomorow → tomorrow
Homophones
Homophones are words that sound the same but have different meanings and spellings. And most of the time, simple online spell-checkers won’t catch them because technically the spelling is correct, but the word choice is wrong. Luckily, the fix is simple: Don’t choose the word that sounds right. Pick a word that means the right thing in the sentence.
Common Homophone Pairs
- their/there/they’re
- your/you’re
- to/too/two
- bare/bear
- advice/advise
- meet/meat
- new/knew
- knight/night
- threw/through
- peace/piece
- hear/here
- right/write
- sale/sail
- break/brake
- one/won
- buy/by/bye
Here’s a closer look at “their/there/they’re” and “to/too”:
- There = place or existence. For example, put it there.
- Their = possession (always shows ownership). For example, their house is blue.
- They’re = contraction of they are. For example, they’re ready. → They are ready.
- To = direction, connection, or verb form. For example, go to school, want to learn
- Too = also / excessive. For example, she came too.
- Two = the number. For example, can you give me two seconds?
Similar Sounding Words
These words don’t sound exactly the same, but they’re close enough to cause confusion. The mistake isn’t spelling, it’s choosing the wrong word.
Here are some common mix-ups
accept/except
- accept = receive or agree
- except = all but / other than
affect/effect
- affect = verb (to influence)
- effect = noun (result)
- effect (verb) = to bring about
advise/advice
- advise = verb
- advice = noun
conscious / conscience
- conscious = awake, aware
- conscience = moral sense
idea/ideal
- idea = thought
- ideal = perfect standard
its/it’s
- its = possessive
- it’s = it is / it has
lead/led
- lead = metal (noun)
- led = past tense of lead (verb)
than/then
- than = comparison
- then = time, sequence, result
‘Or’ and ‘Er’ Confusion
Another common mix-up? Using -er and -or. So, which one should you use? The word should end with an -er if:
- It is a simple action verb.
- It ends in a single consonant.
- It ends in a silent e.
- It ends in most consonant blends.
For example:
- → teach → teacher
- → write → writer
- → build → builder
On the other hand, you should have “-or” at the end if the word has:
- Multiple syllables and ends in “-it” (→ edit → editor)
- Multiple syllables and ends in “-ate”(→ educate → educator)
- Ends in “-ct” (→ act → actor)
Extra Tip: You choose -er or -or by word structure, not pronunciation.
-ible vs -able
Another common mistake is switching “-ible” with “-able” or vice versa. So, how do you know which one to use?
Well, -able is the default in modern English. It’s used when the root word is complete. For example, read becomes readable and enjoy is enjoyable.
On the other hand, -ible is more common with words of Latin origin. Most of the time, you have to change the spelling before adding the suffix. For example, collapse to collapsible.
But there’s always an exception to this rule. Take a look at the word “corrupt.” In order for it to become “corruptible,” you don’t have to change the spelling of “corrupt,” you simply add the suffix “-ible” at the end.
