will follows be ('he is would')

'Is would' (forms like "he's would" or "she is would") is a common slip: two auxiliaries clash. English uses a single auxiliary chain for tense and mood-pick the one that matches time and meaning.

Delete the extra auxiliary and adjust the verb form. Use 'is' + -ing for current actions, 'will' for definite future, and 'would' for hypotheticals, politeness, or conditional results.

Quick answer: never use 'is' + 'would' together

Remove one auxiliary and choose the form that fits your meaning: 'is' + -ing for present progressive, 'will' for definite future or promises, 'would' for hypotheticals or polite phrasing.

• If it's happening now: is + verb-ing - He is running.
• If it's a definite future: will + base - He will run tomorrow.
• If it's hypothetical or conditional: would + base - He would run if he had time.

Core explanation: what's wrong with 'is would'?

'Is' is a present form of be used either as an auxiliary for continuous tenses or as a linking verb. 'Would' is a modal auxiliary that marks conditionality, politeness, or unreal past. They belong to different auxiliary chains. Stacking them creates a tense/mood conflict and produces ungrammatical forms like "He is would...".

Fix it in three steps: expand contractions if any, delete the extra auxiliary, then choose the auxiliary that matches time/mood.

• Present progressive: is + verb-ing → She is preparing the slides.
• Future/factual: will + base → She will prepare the slides.
• Conditional/hypothetical: would + base → She would prepare the slides if asked.

• Wrong → Right: He is would go to the store. → He would go to the store.
• Wrong → Right: She is would like a coffee. → She would like a coffee.
• Wrong → Right: It is would be difficult to finish on time. → It would be difficult to finish on time.

Real usage and tone: pick is, will, or would

Choose by time and certainty: 'is' for current facts/ongoing actions; 'will' for definite future events or commitments; 'would' for hypotheticals, polite requests, or tentative reasoning.

• Work: Use 'will' for deadlines and commitments; use 'would' for contingencies or polite requests.
• School: Use 'is' for current observations, 'will' for planned actions, and 'would' for hypothetical analysis.
• Casual: 'Would' softens offers and preferences; 'is' states what's happening now.

• Work:
  Wrong: She is would finish the report by Friday. → Better: She will finish the report by Friday.
• School:
  Wrong: The student is would turn in the essay late. → Better (conditional): The student would turn in the essay late. → Better (plan): The student will turn in the essay late.
• Casual:
  Wrong: He is would come to the party. → Better (conditional): He would come if he could. → Better (planned): He will come if he can.

Examples: common wrong → right pairs (work, school, casual)

Rewrite help: step-by-step fixes and ready rewrites

Quick checklist to repair a sentence with 'is would': expand contractions, remove one auxiliary, pick is/will/would to match time/mood, and adjust any if-clauses so tenses align.

Try your own sentence

Test the whole sentence, not just the phrase. Context makes the intended auxiliary clear. Expand contractions, then choose the auxiliary that expresses time or conditionality.

Memory tricks and quick rules

Keep two short rules handy while you type: one auxiliary only; decide whether the situation is real or imagined.

• Rule 1 - One Aux, One Meaning: If two auxiliaries appear, delete the one that doesn't match meaning.
• Rule 2 - Real or Imagined? Real → is/will. Imagined/conditional → would.
• Quick test: try replacing the clause with an 'if' sentence. If that feels natural, 'would' is likely correct.

Similar mistakes to watch for

Writers sometimes stack other modals or mix auxiliaries: 'might would', 'will would', 'is will', 'has would'. The fix is the same: choose the single auxiliary that fits and adjust the verb form.

• Wrong: She might would accept the offer. →
  Right: She might accept the offer. OR She would accept the offer (if...).
• Wrong: He will would help. →
  Right: He will help. OR He would help, depending on meaning.
• Wrong: They has would finished. →
  Right: They would have finished.
• Wrong: They've would seen it before. →
  Right: They would have seen it before.

Hyphenation, spacing, and contraction notes

A common source of 'is would' is an expanded contraction that wasn't checked: "he's would" (he's = he is) becomes "he is would". Expand contractions when you proofread to reveal this error.

Hyphens and spacing rarely change auxiliary choice but can hide mistakes when typing quickly. Never hyphenate auxiliary + verb (write "is going", not "is-going").

• If you see "he's would", expand to "he is would" to catch the extra auxiliary.
• Fix stray hyphens or joined words that accidentally create two auxiliaries: remove the extra word or split the clause into two sentences.

Grammar basics: auxiliaries, modals, and conditionals

Auxiliaries form verb chains. Valid patterns include modal + base verb (would go, will go), be + -ing (is going), and have + past participle (has gone). Don't mix a present 'be' form with a modal.

Conditionals short guide: If + present → will in the result clause (If he can, he will). If + past → would in the result clause (If he could, he would). Unreal past uses would have + past participle (She would have passed).

• Modal + base: would + verb → would go.
• Be + -ing: is + verb-ing → is going.
• Perfect conditional: would have + past participle → would have gone.

• Usage: Wrong: She is would have told us. →
  Right: She would have told us.

FAQ

Is 'is would' ever correct?

No. In standard English 'is would' combines a present form of be with a modal and creates a tense/mood conflict. Remove one auxiliary and rewrite as is + -ing, will, or would depending on meaning.

How do I choose between 'will' and 'would' after removing 'is'?

Use 'will' for definite future actions, announcements, or promises. Use 'would' for hypotheticals, politeness, or results tied to a past-tense condition. If an if-clause is present, match tenses: If + present → will; If + past → would.

What should I do if I typed "he's would"?

Expand the contraction (he's → he is), then delete the incorrect auxiliary. Pick 'he will' for a future statement or 'he would' for a conditional or polite sentence.

Will grammar checkers always catch 'is would'?

Most modern checkers flag 'is would' and suggest replacements, but they may not pick the writer's intended meaning. Use the suggestion as a prompt, then confirm whether you want certainty ('will') or conditionality ('would').

Why do learners write double auxiliaries?

Some languages use auxiliary patterns that differ from English, so learners transfer both be and a modal. Practice choosing a single auxiliary and read sentences aloud to build intuition.

Fix one sentence now

When in doubt: expand contractions, ask whether the event is real or imagined, then choose one auxiliary. Paste the sentence into a grammar tool after expanding contractions to check suggestions and confirm meaning.

Use the checklist: one auxiliary, decide real vs imagined, adjust any if-clauses. That usually fixes 'is would' immediately.
