When my students write “he was tieing his shoes,” I know they’re applying a rule they half-remember about doubling consonants or dropping the letter ‘e’. The confusion makes sense — English spelling rules feel unpredictable. But the truth is simpler: “tying” is the only correct spelling. There’s no modern context where “tieing” is acceptable, even though it *looks* like it could be right.
You’ll breaks down why “tying” is correct, shows you the exact rule for verbs ending in “-ie,” and teaches you the broader “-ing” suffix rules so you can spell any gerund accurately. I’ve included real examples, a comparison table, and a practice quiz to lock in your understanding.
Key Takeaways
- Only “tying” is correct — tieing is an obsolete spelling with no place in modern English.
- The rule: verbs ending in “-ie” → change to “-y” before adding “-ing” — tie → tying, lie → lying.
- Why the change? — “-ie” + “-ing” would create “iiing”, which looks wrong; “-y” + “-ing” flows naturally as “ying”.
- Memory hook — “IE to Y”: replace the ‘ie’ with ‘y’ when you see “-ing” coming.
- Apply broadly — the same rule applies to die → dying, pie → (not a verb, but if it were) → pying.
Tying vs. Tieing: Definitions and Core Rule
| Aspect | Tying | Tieing |
|---|---|---|
| Status | ✓ Correct (modern English) | ✗ Incorrect (obsolete) |
| Part of speech | Present participle / gerund | N/A (not used) |
| Meaning | Fastening, securing with a knot, binding | No meaning (incorrect form) |
| Example (correct) | “She is tying her shoelaces.” | Never acceptable |
| Frequency | 100% of modern English writing | Historical texts only |
The “-IE to -Y” Rule Explained
When a verb ends in “-ie” (like “tie,” “lie,” or “die”), you change the “-ie” to “-y” before adding “-ing”. This rule exists because “-ie” + “-ing” would create an awkward “-iiing” sequence that looks and feels wrong in English.
Example 1: The verb “tie” ends in “-ie”. When you add “-ing”, you don’t write “tie-ing” (which would be “tieing”). Instead, you change “-ie” to “-y” and then add “-ing”: “tying”.
Example 2: The verb “lie” follows the same rule. “Lie” becomes “lying”, not “lieing”. “The cat is lying on the bed” — this is correct. “The cat is lieing on the bed” — this is incorrect.
Example 3: The verb “die” also uses this rule. “The flowers are dying in the heat” — correct. “The flowers are dieing” — incorrect, even though some might expect it.
The reason for this rule is that “-ie” and “-i” are often written as “ie” in English (to represent the long “ee” sound). Adding “-ing” directly would create “iiing”, which breaks the visual and phonetic patterns of English. By changing “-ie” to “-y”, we get a familiar and readable form: “tying,” “lying,” “dying.”
Breaking Down the Broader “-ING” Rules
Understanding when to modify a verb before adding “-ing” helps you spell hundreds of words correctly. Here are the main patterns:
Rule 1: Drop the Final “E”
If a verb ends in a silent “e”, drop it before adding “-ing”.
- write → writing
- love → loving
- make → making
- escape → escaping
Rule 2: Change “IE” to “Y”
If a verb ends in “-ie”, change it to “-y” before adding “-ing”.
- tie → tying
- lie → lying
- die → dying
Rule 3: Double the Final Consonant (CVC Rule)
If a one-syllable verb ends in consonant-vowel-consonant (CVC), double the final consonant before adding “-ing”.
- run → running (r-u-n = CVC)
- sit → sitting (s-i-t = CVC)
- swim → swimming (s-w-i-m = CVC)
But NOT: walk → walking (w-a-l-k ends in two consonants, so no doubling). And NOT: help → helping (h-e-l-p, final stress isn’t on ‘p’, so no doubling).
Rule 4: Add “K” After “C”
If a verb ends in “c”, add “k” before adding “-ing” to preserve the hard “c” sound.
- panic → panicking
- picnic → picnicking
- traffic → trafficking
Rule 5: Keep Doubled Consonants
If a verb already has a doubled consonant, keep it when adding “-ing”.
- happen → happening (not hapening)
- occur → occurring (not ocuring)
Why “Tieing” Is Wrong: A Closer Look
The spelling “tieing” violates the “-ie to -y” rule. Here’s the logic:
- The base verb is “tie” (t-i-e).
- Rule: When a verb ends in “-ie”, change it to “-y” before adding “-ing”.
- Correct: tie → ty-ing = “tying”.
- Incorrect: tie + ing = “tieing” (skips the “-ie to -y” conversion).
If you see “tieing” in old or informal writing, it’s a spelling error, not an alternative form. The word has never been acceptable in standard English spelling, even in British vs. American variants.
Tying in Context: Usage as Gerund and Participle
“Tying” functions in two ways in English sentences:
As a Gerund (Noun)
A gerund is a verb form that functions as a noun. When “tying” is a gerund, it’s the subject or object of a sentence.
Example 1: “Tying knots requires practice.” (Tying = subject of the sentence)
Example 2: “She loves tying bows.” (tying = direct object)
Example 3: “He is good at tying shoelaces.” (tying = object of the preposition “at”)
As a Present Participle (Part of a Verb Phrase)
A present participle is part of a continuous (progressive) verb phrase, describing an action in progress.
Example 1: “I am tying my shoes right now.” (continuous present)
Example 2: “She was tying her scarf when the doorbell rang.” (continuous past)
Example 3: “They have been tying decorations all morning.” (present perfect continuous)
Conjugation of “Tie” Across Tenses
| Tense | Conjugation | Example Sentence |
|---|---|---|
| Simple present | tie, ties | I tie my shoes every morning. |
| Simple past | tied | She tied the knot yesterday. |
| Present participle | tying | He is tying his boat to the dock. |
| Present perfect | has/have tied | We have tied three knots so far. |
| Past perfect | had tied | They had tied everything down before the storm. |
Common Mistakes and How to Avoid Them
✗ Incorrect: “He was tieing his shoelaces when I arrived.”
✓ Correct: “He was tying his shoelaces when I arrived.”
Why: “Tie” ends in “-ie”, so you change it to “-y” before adding “-ing”. The correct form is “tying”, not “tieing”.
✗ Incorrect: “She enjoys tieing her hair in a bun.”
✓ Correct: “She enjoys tying her hair in a bun.”
Why: Same rule. “Tying” is a gerund here (the object of “enjoys”). Use “tying”, never “tieing”.
✗ Incorrect: “The farmer is tieing the cows together.”
✓ Correct: “The farmer is tying the cows together.”
Why: This is a continuous verb phrase. The correct participle is “tying”. “Tieing” is never correct in any modern context.
Sample Dialogue
Student: Is it “tieing” or “tying”?
Teacher: Always “tying”. The word “tie” ends in “-ie”, so when you add “-ing”, you change the “-ie” to “-y” first.
Student: But why? That seems random.
Teacher: If you didn’t change it, you’d have “tieing” — three vowels in a row: i-e-i. English doesn’t like that. By changing “-ie” to “-y”, you get “tying” — much cleaner.
Student: So the same rule applies to “lie”?
Teacher: Exactly. “Lie” becomes “lying”, not “lieing”. It’s the same “-ie to -y” rule every time.

Frequently Asked Questions
Is “tieing” ever correct?
No. “Tieing” is never correct in modern English. It is an obsolete spelling that does not appear in any standard dictionary as an acceptable form. The only correct spelling is “tying”.
What rule makes “tying” correct?
Verbs ending in “-ie” change the “-ie” to “-y” before adding “-ing”. So “tie” becomes “tying” (not “tieing”), and “lie” becomes “lying” (not “lieing”). This rule prevents the awkward “-iiing” sequence.
Does the same rule apply to the word “die”?
Yes. “Die” becomes “dying”, not “dieing”. The flowers are dying in the summer heat. This is the same “-ie to -y” rule at work.
Is “tying” only used in continuous tense?
No. “Tying” can be a present participle (part of a continuous verb) OR a gerund (noun). “I am tying my shoes” (participle). “Tying knots is fun” (gerund). Both are correct uses.
How do I remember this rule?
Think of it as the “IE to Y rule”: when you see a verb ending in “-ie” and need to add “-ing”, replace the “-ie” with “-y”, then add “-ing”. Tie → Ty → Tying. Simple and consistent.
