Skiddish or Skittish: Which Is Correct?

The adjective meaning nervous, jumpy, or easily startled is skittish, spelled with a double t. The version skiddish, with dd, is a misspelling: it is not a word, and no dictionary lists it. Whether you are describing a nervous animal ("the horse was skittish around the crowd"), an anxious person ("she felt skittish before the interview"), or a jittery financial market ("investors turned skittish"), the correct spelling keeps the tt: skittish. The error happens because of the word skid, with its d: a skidding car slides and lurches unpredictably, which feels a lot like the jumpy, out-of-control quality that skittish describes. That false connection leads writers to swap the tt for dd and produce skiddish. But skittish has nothing to do with skid. It comes from the old word skit, meaning to move quickly or shy away, and keeps that t, doubled before -ish. This places skiddish vs skittish among the commonly confused words where a similar-sounding word pulls the spelling toward the wrong consonant. This guide explains what skittish means, why skiddish tempts people, and an easy way to keep the tt.

Which Spelling Is Correct?

Skittish is the correct spelling, and skiddish is always a misspelling. In every use, a skittish colt, a skittish reaction, a skittish stock market, the word is skittish, with tt. There is no context in which skiddish is acceptable, because the dd version is not a recognized English word.

The reason lies in the word's root. Skittish derives from the Middle English skit, meaning to move rapidly, to dart, or to shy away, the same root behind skittery, skitter, and skittle. Adding the adjective ending -ish to skit, with the final t doubled (as commonly happens before -ish on a short stressed syllable), gives skittish. The t is inherited directly from skit and is fixed.

The mistaken skiddish wrongly aligns the word with skid, an unrelated word meaning to slide uncontrollably. Skid has a d, and a skid does feel jumpy and unstable, but it is not the source of skittish. The two words look and sound somewhat alike and share a loose sense of erratic movement, which is exactly the trap. Recognizing that skittish belongs to the skit/skitter family, not the skid family, is the key to keeping the tt.

What the Word Means

Skittish is an adjective describing nervous, restless, easily startled behavior, a tendency to react with sudden alarm or to shy away. It clusters around a few common uses.

Its oldest and most literal use is of animals, especially horses: a skittish animal is jumpy and easily frightened, liable to bolt or flinch at sudden movements or noises. "The mare was skittish near the traffic," "a skittish pony," "the deer grew skittish as we approached." Here it names a wary, flighty temperament.

Applied to people, skittish means nervous, jittery, or hesitant, easily made anxious or quick to back away: "he was skittish about commitment," "she felt skittish before going on stage," "the crowd turned skittish at the sound." It can suggest both fearfulness and a kind of restless unease.

By extension, skittish describes markets, economies, and moods that are volatile and easily spooked: "investors were skittish after the news," "a skittish market sold off sharply," "consumer confidence is skittish." Here it means liable to sudden, nervous swings.

It can even mean playfully frisky or capricious in older usage, though the dominant modern sense is nervous and easily startled. Across all these uses, animals, people, markets, the spelling is skittish, with tt. There is no skiddish for any sense; the double t is constant.

Why People Misspell It

If skittish is the only correct form, why does skiddish appear? The cause is the strong pull of the word skid, reinforced by sound and meaning.

The main driver is the resemblance to skid. Both words start with ski-, and a skid, a car sliding out of control, evokes exactly the kind of sudden, jumpy, unstable motion that skittish describes. So the connection feels doubly right: the words look alike and their meanings seem related. Writers reach for the familiar skid and carry its d into the adjective, producing skiddish. The semantic overlap, both about erratic, uncontrolled movement, makes the wrong spelling especially sticky.

A second cause is sound. The double t in skittish is pronounced as a quick tap that, in many accents, sounds close to a d (the same "flapping" that makes latter sound like ladder). So skittish spoken aloud can sound a little like it has a d in the middle, nudging writers toward skiddish when they spell by ear. The pronunciation does not clearly signal tt over dd.

A third factor is that the true root, skit, is unfamiliar; few people know the word skit in its old sense of darting away, so they have no obvious anchor for the t. Without that, the well-known skid fills the gap. The cure is to connect skittish to skitter and skittery, words people do recognize, all with the tt and all about quick, jumpy movement, so the double t has a familiar home.

Examples in Sentences

Seeing skittish spelled correctly across its senses, with the skiddish error corrected, fixes the right form.

Correct uses of skittish:

• The horse was too skittish to saddle.
• He gets skittish whenever the topic comes up.
• Markets turned skittish ahead of the announcement.
• The cat is skittish with strangers.

Correct related skit- words:

• The mice skittered across the floor.
• She has a skittery, restless energy.

Wrong → right corrections:

• The pony was skiddish in the storm. → The pony was skittish in the storm.
• Investors grew skiddish overnight. → Investors grew skittish overnight.
• Don't be so skiddish about it. → Don't be so skittish about it.

In every correction, the dd is replaced by the correct tt. The meaning, nervous and easily startled, never changes; only the spelling is brought back to the skit root.

Skittish vs Skiddish: Side by Side

The table sets the correct spelling against the dd error and shows what separates them.

Aspect	Skittish (correct)	Skiddish (incorrect)
Middle consonant	tt	dd
Status	Standard English word	Misspelling, not a word
Root	skit ("to dart, shy away")	(wrongly tied to skid)
Related words	skitter, skittery, skittle	(skid, but unrelated)
Meaning	nervous, easily startled	none, just misspelled
In dictionaries?	Yes	No

The decisive row is the root: skittish comes from skit and keeps the tt, like skitter and skittery. Skiddish wrongly borrows the d of skid, an unrelated word.

How to Remember

The cleanest trick is to link skittish to skitter and skittery, words about quick, jumpy, darting movement, all spelled with tt. A skittish animal skitters away; the shared skit root and double t tie them together. When skiddish tempts you, recall that the nervous creature skitters (with tt), not skids, and the correct spelling follows.

A second guard is to consciously reject the skid link. Yes, a skid and a skittish horse both seem jumpy and unstable, but the words are unrelated: skittish is built on skit (to dart), not skid (to slide). Remind yourself that the root has a t, not a d, "skit, not skid", and double the t before -ish. The flapped pronunciation may sound like a d, but the spelling keeps tt. Between the skitter/skittery family and the "skit, not skid" check, the correct skittish stays locked in.

Related Spelling Mixups

Skiddish vs skittish belongs to a family of errors where a similar-sounding word pulls the spelling toward the wrong consonant. If this one tripped you, two related cases are worth a look. The first is saucey vs saucy, where an extra letter sneaks into a short, casual adjective. The second is compair vs compare, where a familiar sound pulls the spelling toward the wrong ending. Each, like skittish, rewards knowing the word's actual root, rather than letting a lookalike, here skid, reshape the spelling.

Conclusion

The adjective meaning nervous, jumpy, or easily startled is skittish, spelled with a double t, and skiddish, with dd, is always a misspelling. The error is natural because of the word skid: a skidding car lurches and slides in exactly the unstable, jumpy way that skittish describes, so the two seem connected, and the flapped pronunciation of the tt can even sound like a d. But skittish has nothing to do with skid; it descends from the old word skit, meaning to dart or shy away, and belongs to the skitter/skittery family, all spelled with tt. The reliable cure is to picture the skittish animal skittering away, and to remember the root is skit, not skid, a t, not a d. Keep that in mind, and skittish will come out right every time, whether you mean a flighty horse, an anxious person, or a jittery market.
