Question 1

What is the difference between wish and if only?

Accepted Answer

"Wish" and "if only" have the same meaning and follow the same grammar rules. The main difference is emphasis: "if only" sounds more emotional and dramatic. Compare: "I wish I could come to the party" (neutral regret) and "If only I could come to the party!" (stronger feeling of disappointment). In everyday English, "wish" is more common. "If only" often appears at the start of a sentence and is followed by an exclamation mark to show strong emotion. Both can be used with past simple for present wishes and past perfect for past regrets. In Cambridge B1 exams, you need to know both forms.

Question 2

Why do we use past tense after wish for present situations?

Accepted Answer

English uses "unreal past" — past tense forms that do not refer to the past. After "wish," the past simple shows that the situation is imaginary or opposite to reality. "I wish I knew the answer" uses past tense "knew," but the meaning is present: right now, I do not know the answer. This same pattern appears in second conditional sentences: "If I knew the answer, I would tell you." The past tense signals unreality, not past time. This is why "I wish I know" is always wrong — the present tense cannot express an unreal situation. Think of it as a grammar signal: past form equals imaginary meaning.

Question 3

Do I use was or were after wish?

Accepted Answer

In formal English, use "were" for all subjects after "wish": "I wish I were," "she wishes he were," "if only it were." This formal "were" form is considered correct in exams and academic writing. In informal spoken English, many native speakers say "I wish I was" — this is widely accepted in conversation but may be marked wrong in a grammar test. For Cambridge and IELTS examinations, always use "were" to be safe. The same rule applies after "if only" and in second conditional sentences: "If I were you, I would apologise."
