The correct spelling is noticeable—the spelling noticable is an incorrect error with no standing in modern English dictionaries. The silent e is preserved when adding the suffix -able to maintain the soft “c” sound (/s/) in notice.
Standard spelling rules dictate dropping the silent “e” before a vowel suffix (as in make → making or love → lovable), but English makes a necessary exception for words ending in -ce or -ge. If the e were dropped to form noticable, the letter c before an a would turn into a hard “k” sound (making it sound like “no-tik-uh-bull”). To keep the original sound intact, the word is always spelled N-O-T-I-C-E-A-B-L-E.

Why Is “Noticeable” Frequently Misspelled as “Noticable”?
The confusion comes from overapplying one of the most common spelling rules taught in English classrooms:
The “Drop the Silent E” Rule Conflict
Students learn that when a base word ends in a silent e, you drop that e before adding a suffix starting with a vowel:
- value + -able = valuable
- adore + -able = adorable
- use + -able = usable
Applying this rule without considering the preceding consonant makes writers naturally drop the e in notice, resulting in noticable.
The Soft “C” and Soft “G” Rule Exception
In English phonics, the letters c and g have two primary sounds depending on the vowel that follows them:
- Hard Sound (before a, o, u): cat, cot, cut (/k/ sound)
- Soft Sound (before e, i, y): cent, city, cyst (/s/ sound)
When attaching the suffix -able (which starts with a), dropping the e forces the c into contact with the a, turning it into a hard /k/. Keeping the silent e acts as a phonetic shield that preserves the soft /s/ sound.
┌── Drop the 'e' -> *Noticable = /noʊˈtɪk.ə.bəl/ (INCORRECT)
NOTICE
└── Keep the 'e' -> Noticeable = /ˈnoʊ.tɪ.sə.bəl/ (CORRECT)
Proven Memory Tricks (Mnemonic Devices)
To ensure this word is spelled correctly in tests, essays, and professional correspondence, use these quick mental aids:
- “Keep the entire word NOTICE, then add ABLE.”Do not modify the root at all:
notice+able= noticeable. - “The ‘E’ is noticeable, so don’t leave it out!”Remind yourself that the letter e is clearly visible and noticeable right in the middle of the word.
- “Without the E, it sounds like NO-TIK-ABLE.”If you remove the e, the hard c makes the word sound absurd.
Part-of-Speech Breakdown & Definition
Noticeable functions as an adjective.
| Part of Speech | Definition | Example Sentence | Pronunciation |
| Adjective | Easily seen, observed, or detected; attractively striking | There was a noticeable improvement in her test scores this term. | /ˈnoʊ.tɪ.sə.bəl/ |
Derivatives and Related Words
The silent e is retained across all related word forms that preserve the root:
- Noticeably (Adverb):“The weather grew noticeably colder as we climbed higher up the mountain.”(Incorrect: ~~noticably~~)
- Unnoticeable (Adjective):“The tiny scratch on the car door was virtually unnoticeable.”(Incorrect: ~~unnoticable~~)
- Unnoticeably (Adverb):“The background music faded out unnoticeably as the speaker stepped onto the stage.”(Incorrect: ~~unnoticably~~)
Other Words Following the Soft “C” & “G” Suffix Rule
Noticeable is not an isolated case. The same phonetic rule applies to these words:
- Changeable (change + able) — Keeps the e to preserve the soft “j” sound.
- Peaceable (peace + able) — Keeps the e to preserve the soft “s” sound.
- Manageable (manage + able) — Keeps the e to preserve the soft “j” sound.
- Serviceable (service + able) — Keeps the e to preserve the soft “s” sound.
- Knowledgeable (knowledge + able) — Keeps the e to preserve the soft “j” sound.
