every (ever) since

Short answer: use "ever since". "Every since" is nonstandard because "every" needs a noun to modify.

Quick answer

Replace any "every since" with "ever since" or rewrite the sentence.

ever is an adverb that pairs with since to mean "from that time to now."
every is an adjective that must modify a noun (e.g., "every day").
If a direct swap sounds odd, use a rewrite pattern (examples below).

Core explanation: why "ever since"

"Ever" modifies time or verbs; paired with "since" it points to continuous action from a specific moment: "ever since the launch." "Every" modifies items-"every day," "every year"-so "every since" has no noun to modify and breaks grammatical agreement.

Use "ever since" when you mean "from that time to now."
Use "every" only before a noun: "every week," "every student."

Wrong: I've followed her music every since she released her first album.
Right: I've followed her music ever since she released her first album.

Rewrite patterns - when a swap isn't enough

Three reliable patterns to fix awkward sentences.

Pattern A: ever since + clause - keeps the original structure.
Pattern B: since + [event/date] - clearer or more formal: "since the release"
Pattern C: since then - short when the event is already clear.

Rewrite 1: Wrong: He's been late every since he transferred teams. → A: He's been late ever since he transferred teams.
Rewrite 2: Wrong: We've lost momentum every since the vendor issue. → B: We've lost momentum since the vendor issue began.

Hyphenation, spacing and punctuation notes

"Ever since" is two words. Do not hyphenate (ever-since) or combine (eversince).

Comma rules: use a comma after an introductory time clause - "Ever since the update, the site has been slow." No comma is needed when the clause follows the verb unless it improves clarity.

Correct: ever since (two words).
Avoid: every since (incorrect), ever-since (nonstandard).

Hyphen wrong: Ever-since the rollout the site has been sluggish.
Hyphen right: Ever since the rollout, the site has been sluggish.

Try the one-word swap first. If the sentence still feels clunky, apply a rewrite pattern.

Exercise (work): Original: The client has complained every since we changed the specifications. Swap: The client has complained ever since we changed the specifications.
Alternative: Since we changed the specifications, the client has complained.
Exercise (school): Original: My grades dropped every since the lab moved online. Fix: My grades dropped ever since the lab moved online. Or: My grades dropped after the lab moved online.
Exercise (casual): Original: I've had trouble sleeping every since the new neighbors moved in. Fix: I've had trouble sleeping ever since the new neighbors moved in. Short: Since the neighbors moved in, I've had trouble sleeping.

Memory tricks and similar mistakes

Mnemonic: ever = time/adverb; every = each/adjective. If you point to a moment, pick ever. If you point to items, pick every.

Watch related confusions: "since" vs "for" (point vs duration), "every day" vs "everyday" (two words vs adjective).

If you can replace the phrase with "from that time" or "since then" and keep the meaning, "ever since" is likely correct.
Watch: "every week" (correct) vs "everytime" (wrong - write "every time").

Similar 1: Correct: I've known her since 2018.
Correct: I've known her for four years. (since = point; for = duration)
Similar 2: Correct: Every day I practice. Wrong as adjective: Everyday I practice. (use "every day" for "each day")

Most of the time yes. If the sentence still reads awkwardly, use one of the rewrite patterns: "since [event]," "since then," or restructure the clause.
