Complete the detective's response to the prime suspect's rather creative alibi. Select the grammatically correct phrase.

"You claim you were abducted by aliens during the museum heist. ____, you still left your fingerprints on the display case."

The correct answer is Be that as it may.

"Be that as it may" is a fossilized expression using the present subjunctive ("be"). It functions as a concessive phrase, meaning "even if that is true" or "nevertheless." The other options do not grammatically exist in this fixed idiom.

Subjunctive mood

  • If I were you… — past subjunctive (not was)
  • I suggest that he go. — present subjunctive (not goes)
  • It's important that she be present. — present subjunctive
  • If I was you… — common in speech, avoided in formal writing

The subjunctive uses bare-infinitive forms (go, be) after verbs of demand/suggestion, and were (not was) in unreal/hypothetical conditions. Two contexts: that-clauses (I insist that he leave) and if-clauses (If she were here).

Rule: after suggest/recommend/demand/insist that… → use base form. In if + unreal condition → use were for all persons.

Verb mood

  • Indicative: She goes every day. — stating fact
  • Imperative: Go now. — giving command
  • Subjunctive: I suggest she go. — hypothetical/recommendation
  • Conditional: She would go if asked. — dependent on condition

Verb mood marks the speaker's attitude: indicative (fact), imperative (command), subjunctive (unreal/recommended), conditional (would/could). English barely marks mood morphologically — mostly through auxiliaries and word order.

Rule: stating a fact? → indicative. Giving a command? → imperative. Imagining/recommending? → subjunctive or conditional. The mood determines which verb forms and auxiliaries you use.

Phrase

  • the red car — noun phrase (functions as one noun unit)
  • on the table — prepositional phrase
  • has been running — verb phrase
  • very quickly — adverb phrase

A phrase is a group of words that functions as a single unit WITHOUT a subject + verb pair. Types: noun phrase, verb phrase, prepositional phrase, adjective phrase, adverb phrase.

Key distinction: a phrase lacks a subject-verb pair. If it has subject + verb → it's a clause, not a phrase. Phrases are the building blocks clauses are made of.

Verb

  • walk → walk / walks / walked / walked / walking (5 forms, regular)
  • go → go / goes / went / gone / going (5 forms, irregular)
  • be → am/is/are/was/were/be/being/been (8 forms)
  • can → can / could (modal: only 2 forms, no -s, no -ing)

A verb is the one word class every English sentence requires. Carries tense (when), aspect (duration), mood (attitude), and voice (active/passive). Regular verbs add -ed; ~200 irregular verbs have unpredictable past forms.

Key insight: fix your verbs and most grammar problems disappear. Wrong tense, wrong agreement, wrong form — verb errors account for the majority of grammatical mistakes.

Idiom

  • It's raining cats and dogs. — means "raining heavily" (not literal animals)
  • Break a leg! — means "good luck" (not an injury wish)
  • Spill the beans — means "reveal a secret"
  • Kick the bucket — means "to die" (no actual bucket involved)

Idioms are fixed phrases whose meaning can't be guessed from the individual words. They must be memorised as complete units — word-by-word translation from another language almost always fails.

Pattern: if a phrase is literally absurd but everyone uses it with a specific meaning → it's an idiom. Learn it as a chunk, not as individual words.

C1 | Advanced

  • Not only did she finish early, but she also helped others. — inversion for emphasis
  • It is the process that matters, not the result. — cleft sentence
  • I insist that he be present. — formal subjunctive
  • Were I to disagree, I would say so. — inverted conditional

These are C1 structures — the CEFR advanced level. At C1 you control inversion, cleft sentences, subjunctive forms, and register-switching fluently across formal and informal contexts.

Marker: if you can restructure a sentence for rhetorical effect without hesitation, you're C1.

Hard

  • Had she not intervened, the situation would have escalated. — inverted conditional
  • All distractors are grammatically plausible in other contexts
  • Multiple rules interact (e.g., tense + aspect + modality)
  • Context determines the answer — no single "rule" is enough

Hard marks upper-intermediate to advanced challenges: B2+, interacting rules, edge cases, plausible distractors, and contexts where pattern-matching fails.

Use "Hard" when Easy/Medium feel trivial and you want to test whether you actually understand a rule versus just recognising surface patterns.
