✦Grammar Breakdown
Ascriançasdeveriamsaberdoplano?
Definite Article (As)
‘As’ is the feminine plural definite article, used before plural feminine nouns like ‘crianças’.
Noun (crianças)
‘crianças’ means ‘children’; it is feminine plural, so it matches the article ‘as’.
Conditional Verb (deveriam)
‘deveriam’ is the conditional form of ‘dever’ (should/ought to), agreeing with a plural subject.
Infinitive (saber)
‘saber’ is the infinitive ‘to know’; after a modal verb like ‘dever’, the infinitive follows directly.
Preposition + Article (do)
‘do’ = ‘de’ (of) + ‘o’ (the); it contracts before masculine singular nouns.
Noun (plano)
‘plano’ means ‘plan’; it is masculine singular, so it takes the article ‘o’, forming ‘do plano’.

✕Common Mistakes
As crianças deveriam sabe do plano?
After ‘deveriam’, the verb must stay in infinitive form; ‘sabe’ is a conjugated present tense.
As crianças deveriam saber sobre o plano?
‘Sobre o plano’ is acceptable but changes the nuance; the original phrase uses ‘do plano’ (of the plan) which is more concise.
As crianças deveria saber do plano?
‘Deveria’ is singular; the subject ‘as crianças’ is plural, so the verb must agree: ‘deveriam’.

Cultural Tip
In Brazilian Portuguese, using the conditional ‘deveriam’ sounds more tentative and polite than the direct ‘precisam’. It’s common to soften suggestions when speaking to parents or educators, showing respect for their authority over the children.
