Fact-Checking 'How Comes': Historical Archaism or Outright Grammatical Flub?
By Marcus Vance
Q1: Is "how comes" ever considered correct in modern standard English?
No. Standard English grammar recognizes "how come" as the sole acceptable form of this idiom. Major dictionaries, including Merriam-Webster and Oxford, list "how comes" as dialectal, non-standard, or a spoken colloquial error.
Q2: Why does "how come" not require the verb to change for past tense?
The phrase has fossilized into an invariable idiomatic compound. Because it acts as an interrogative complementizer rather than an active verb in the sentence, it never changes to "how came" regardless of when the action occurred.
Q3: How do you fix a sentence that uses "how comes"?
Simply drop the trailing "s." Change "How comes you decided to resign?" to "How come you decided to resign?" In formal writing, replace it entirely with "Why did you decide to resign?"
Q4: Why does "how come" avoid the inverted sentence structure of "why"?
"How come" is an elliptical shortening of "How comes it that [clause]." In that original structure, the clause following "that" was subordinate and maintained declarative subject-verb order. That declarative order survived even after the middle words disappeared.
