The sentence is expressing a desire or a regret for something that is not true in the present moment. The pattern is "I wish I could ..." so the correct answer is could speak.
Modal Verb
English has the modal verbs can, could, may, might, must, shall, should, will, would, and also (depending on classification adopted) ought (to), dare, need, had (better), used (to). These do not add -s for the third-person singular, and they do not form infinitives or participles; the only inflection they undergo is that to a certain extent could, might, should and would function as preterites (past tenses) of can, may, shall and will respectively.
A modal verb can serve as the finite verb introducing a verb catena, as in "he might have been injured then". These generally express some form of modality (possibility, obligation, etc.), although will and would (and sometimes shall and should) can serve – among their other uses – to express future time reference and conditional mood.
Subjunctive Mood
The subjunctive mood in English is used to form sentences that do not describe known objective facts, but rather wishes or hypothetical suppositions. These include statements about one's state of mind, such as opinion, belief, purpose, intention, or desire. The subjunctive mood, such as She suggests that he speak English, contrasts with the indicative mood, which is used for statements of fact, such as He speaks English.
In Modern English, the subjunctive form of a verb often looks identical to the indicative form, and thus subjunctives are not a very visible grammatical feature of English. For most verbs, the only distinct subjunctive form is found in the third person singular of the present tense, where the subjunctive lacks the -s ending: It is necessary that he see a doctor (contrasted with the indicative he sees). The verb be, however, has not only a distinct present subjunctive (be, as in I suggest that he be removed) but also a past subjunctive were (as in If he were rich, ...).
These two tenses of the subjunctive have no particular connection in meaning with present and past time. Terminology varies; sometimes what is called the present subjunctive here is referred to simply as the subjunctive, and the form were may be treated just as an alternative irrealis form of was rather than a past subjunctive.
Another case where present-subjunctive forms are distinguished from indicatives is when they are negated: compare I recommend that they not enter the competition (subjunctive) with I hope that they do not enter the competition (indicative).
Past Subjunctive Mood
The only distinct past subjunctive form in English (i.e., form that differs from the corresponding past indicative) is were, which differs when used with a first or third person singular subject (where the indicative form is was). As with the present subjunctive, the name past subjunctive refers to the form of the verb rather than its meaning; it need not (and in fact usually does not) refer to past time. The main use of the past subjunctive form, were, which is also known as the irrealis is in counterfactual if clauses:
- If I were your wife, I would put poison in your coffee. [Attributed to Lady Astor, speaking to Winston Churchill]
The simple (indicative) past form was is very common in sentences of this type, though the Random House College Dictionary states "Although the [were] subjunctive seems to be disappearing from the speech of many, its proper use is still a mark of the educated speaker." When were is used, an inverted form without if is possible; this is not possible with was.
A common expression involving were is if I were you. The same principles of usage apply to the compound past subjunctive form were to..., which appears in second conditional condition clauses, usually with hypothetical future reference:
- If she were to go... or Were she to go... (equivalent to if she went)
The past subjunctive form may be used similarly to express counterfactual conditions after suppose, as if, as though, unless, imagine etc.
- Suppose that I were there now.
- She looks as though she were going to kill him.
- Try to imagine he were here.
- Try to imagine a tool that** made** that easy for citizens.
There is also the set expression as it were.
The past subjunctive can also be used in some that clauses expressing a wish contrary to fact or unlikely to be fulfilled:
- I wish [that] he were here now.
- If only the door were unlocked.
- I would rather [that] she were released.
- Would that it were true!
- Oh that it were so.
However, the use of the subjunctive with words such as wish is seldom obligatory. The example with would rather can be cast in the present subjunctive, expressing greater confidence that the action is feasible:
- I would rather she be released.
B2 | Upper Intermediate
B2, or Upper Intermediate, is the fourth level on the CEFR scale. It marks the point where you move from "getting by" to genuinely comfortable communication — handling complex topics, expressing nuanced opinions, and understanding most of what you read or hear in real-world contexts.
What a B2 user can do
At this level, you're expected to:
- Understand complex texts on both concrete and abstract topics, including technical discussions in your own field.
- Follow extended speech and lectures, even when the structure isn't entirely clear, as long as the topic is reasonably familiar.
- Interact fluently and spontaneously enough that conversations with native speakers flow naturally — without strain on either side.
- Produce clear, detailed text on a wide range of subjects, using connectors and cohesive devices to build well-structured arguments.
- Explain and defend a viewpoint on a topical issue, weighing the advantages and disadvantages of different options.
- Recognize implicit meaning — reading between the lines in demanding, longer texts.
What B2 grammar looks like in practice
B2 is where grammar stops being about isolated rules and starts being about flexibility and precision. You're expected to control structures like:
- Advanced conditionals and mixed conditionals — moving beyond simple if-clauses to express hypothetical and counterfactual meaning.
- Passive voice in varied tenses and contexts, not just present and past simple.
- Reported speech with correct sequence of tenses, including backshifting and reporting verbs.
- Participle clauses and the distinction between participles and gerunds.
- Comparative and superlative structures beyond basic -er/-est, including double comparatives and qualifying expressions.
Errors still happen at B2, but they rarely cause misunderstanding. The goal is controlled, flexible use of language across social, academic, and professional settings.
How B2 fits in the CEFR progression
B2 builds directly on the foundations of B1 (Intermediate) and prepares you for C1 (Advanced). Many university entrance exams, professional certifications, and immigration requirements target B2 as the minimum standard.
Self-check: If you can read a newspaper editorial, follow most of a TED talk without subtitles, and write a clear essay arguing a position — you're likely operating at B2.
