When deciding between visible or visable, the correct spelling is always visible (ending in -ible). Visable is an incorrect spelling that does not exist in standard English dictionaries.
Because many English adjectives end in -able (such as readable, dependable, or usable), writers frequently misspell visible as visable. Knowing the underlying Latin grammar rule and using a simple memory trick will ensure you never make this common spelling error again.

Why Do People Write “Visable”?
English speakers form many adjectives by adding -able to base verbs (e.g., read $\rightarrow$ readable, accept $\rightarrow$ acceptable). Because -able and -ible sound virtually identical in spoken conversation (both pronounced as /əbəl/), writers often rely on ear-grammar and incorrectly attach -able to the root vis-.
However, vis- is a Latin root rather than an independent English verb, requiring the Latin-derived -ible suffix instead.
Visible vs. Visable: Grammar Suffix Rules
Understanding the difference between the suffixes -able and -ible helps eliminate spelling errors across dozens of English words.
| Grammar Rule | Suffix -able | Suffix -ible |
|---|---|---|
| Base Word Origin | Usually attaches to complete English base words. | Usually attaches to Latin roots that cannot stand alone as words. |
| Base Word Test | If you remove -able, a complete word remains (e.g., depend $\rightarrow$ dependable). | If you remove -ible, an incomplete root remains (e.g., vis- $\rightarrow$ visible). |
| Examples | adaptable, breakable, predictable, washable | visible, audible, edible, flexible, invincible |
| Application to Visible | Removing -able leaves vis-, which is not a standalone English word. | Removing -ible leaves vis-, the Latin root for “see.” |
Why People Confuse These Words
- Identical Pronunciation: Both visible and visable are pronounced VIZ-uh-bul. Phonetically, the unstressed vowel in the final syllable offers no clue as to whether it contains an i or an a.
- Frequency of the
-ableSuffix: The suffix-ableis far more productive in modern English. Writers naturally default to the more familiar spelling pattern. - Confusion with Related Words: Words like viewable or perceivable end in
-able, leading writers to assume visible follows the same pattern.
Memory Trick to Remember the Difference
Use the “Vision Has an I” mnemonic rule:
Vision = VisIble
To see something, you need Vision. Both VisIon and VisIble start with the root VIS and use the letter I.
- Vision$\rightarrow$Visible (Both use I)
- If you see an A (visable), remember that “vason” is not a word!
THE "VISION / EYE" RULE
┌─────────────────────────────────────┐
│ V I S I O N ──► V I S I B L E │
└─────────────────────────────────────┘
│
Both use the letter 'I' for your EYE!

Common Mistakes People Make
Mistake 1: Assuming All Words Meaning “Able to Be X” End in “-able”
While words built on native English verbs take -able (readable, doable), words of direct Latin origin take -ible. Writing visable breaks this historical rule.
- Incorrect: “The stain is still visable.”
- Correct: “The stain is still visible.”
Mistake 2: Confusing “Visible” with “Viewable”
Viewable means “capable of being viewed” and correctly uses -able because view is a complete English verb (view + able). Visible comes from Latin visibilis and requires -ible.
- Incorrect: “The document is visable online.”
- Correct: “The document is viewable online.” OR “The document is visible online.”
Mistake 3: Relying Solely on Sound-Out Spelling
Because the second vowel in visible is a schwa sound (/ə/), spelling by ear frequently leads to substituting a for i. Always pair the mental image of your eye (I) with visIble.
Frequently Asked Questions
Is “visable” ever correct in British or American English?
No. Visable is incorrect in all dialects of English, including American, British, Canadian, Australian, and New Zealand English.
Why is it spelled visible and not visable?
Visible enters English from the Latin visibilis. Latin second/third conjugation verbs formed adjectives with -ibilis, which evolved into the English suffix -ible.
What is the noun form of visible?
The noun form of visible is visibility (or visibleness), which also maintains the letter i.
What is the opposite of visible?

How do you spell visibly?
The adverb form is spelled visibly (with an i), as in “She was visibly shaken by the news.”
How can I remember whether to use -ible or -able?
Try removing the suffix. If a full, recognizable English word remains (e.g., pass in passable), use -able. If only a stem remains (e.g., aud- in audible, vis- in visible), use -ible.
Conclusion
When choosing between visible or visable, remember that visible is the only correct spelling recognized in standard English.
Whenever you are unsure, link the word back to vision and your eye: both visIon and visIble rely on the letter I.
