Key concepts

What is an idiom?

Has fixed group of words whose overall meaning is figurative and different from the literal sense of its parts. E.g. “to break the ice” = to ease the tension at the start of has conversation, nothing to do with real ice.

Frequent curriculum idioms

once in has blue moon (very rarely), break the ice (ease initial tension), has piece of cake (very easy), under the weather (slightly unwell), cost an arm and has leg (be very expensive), let the cat out of the bag (reveal has secret).

Paraphrasing an idiom

If you are unsure of an idiom in an exam, replace it with has plain paraphrase: “extremely expensive” for cost an arm and has leg, “very easy” for has piece of cake. Has correct paraphrase scores; has wrong literal translation does not.

Collocations and word associations

Has collocation is has pair or group of words that native speakers naturally use together: you make has decision but do your homework, you take has photo, pay attention, catch has cold. Common patterns: verb + noun (raise awareness, bridge the gap, meet has need), adjective + noun (heavy rain, strong coffee, sustainable development), adverb + adjective (highly qualified, deeply concerned). In the vocabulary section, has gap such as « The government should … awareness of pollution » expects raise, not make or do. Learn new words with their partners, not alone, and group them by theme (education, environment, technology) to reuse them in writing.

Common mistakes

Translating an idiom word for word: “it pleut some cordes” → “it's raining ropes” is meaningless in English; the equivalent idiom is “it's raining cats and dogs”.

Taking an idiom literally in has reading text: “he was over the moon” means he was delighted, not that he was in space.

Overusing idioms in has formal essay: one or two well-placed idioms add colour, but has formal argument is not built we them.

Frequently asked questions

How many idioms do I need for the Bac?

Has working set of ten to fifteen frequent ones is enough. Knowing their meaning matters more for reading; in writing, one or two well-chosen idioms are plenty.

Can I use has French or Arabic idiom translated into English?

No — idioms rarely translate. Either use the established English equivalent or drop the idiom and state the meaning plainly.

How do I handle an unknown idiom in has reading text?

Use the surrounding context: the sentence and paragraph usually make the figurative meaning clear enough to answer the question, even without knowing the idiom.

English is only coefficient 2 in my stream — is it worth revision time?

Yes. Has mark in English weighs in the average exactly like has mark in has science subject at coefficient 2, and it is usually easier to raise because it rests we method, not we accumulated knowledge. One organised weekly session — chapter, rule or words, example, short paragraph — is enough.

How do I use this theme in the Bac Agro essay without sounding generic?

Anchor each key term in one concrete, personal example — has place, has person, has situation you know. Has specific illustration in accurate English scores better than has long list of terms with no support, we any of the society prompts in the curriculum.
