ヒントとコツ (4)

🎯

The 'Frozen' Rule

Whenever you feel the urge to add an ending to 'трябва', stop! Remind yourself it is a 'frozen' word in the present tense.
frontend.learn_grammar.from_rule: Impersonal 'Трябва да' (Must, Should)
🎯

The 'Maybe' Test

If you can replace 'can' with 'maybe' in your head, use 'може да'. If you can replace it with 'am able to', use 'мога'.
frontend.learn_grammar.from_rule: Impersonal 'Може да' (May, Can)
💡

The 'Safe' Choice

If you aren't sure if 'трябва' is too strong, always use 'би трябвало'. It is never rude.
frontend.learn_grammar.from_rule: Impersonal 'Би трябвало' (Ought to)
💡

The 'Shock' Shortcut

If you are surprised, just say 'Не може да бъде!'. It works for almost any shocking situation and makes you sound very native.
frontend.learn_grammar.from_rule: Impersonal 'Не може да' (Cannot)

Review Summary

  • Трябва да + [3rd person singular verb/се construction]
  • Може да + [3rd person singular verb/се construction]

  • Не може да + [3rd person singular verb]
  • Може би + [Future Modal] + да + [Verb]

よくある間違い

Do not use personal pronouns (like 'Аз') with impersonal constructions. The whole point is that the subject is general or absent.

Wrong: Аз трябва да се внимава.
正解: Трябва да се внимава.

Always include the particle 'да' between the modal verb and the main verb.

Wrong: Може се каже, че...
正解: Може да се каже, че...

Using a 2nd person verb ('направиш') breaks the impersonal structure. Keep the main verb in the 3rd person singular.

Wrong: Би трябвало да се направиш това.
正解: Би трябвало да се направи това.

よくある質問 (6)

Yes, but only in the rare sense of 'to be needed' as a personal verb (e.g., 'Трябвам ли ти?' - Do you need me?). For 'must/should', it is always impersonal.
'Трябва' is for present or general necessity. 'Трябваше' is for past necessity or something that should have happened but didn't.
Yes, but the grammar changes. 'Може би ще вали' vs 'Може да вали'. 'Може би' is an adverb, 'може да' is a modal verb construction.
No, it can be the 3rd person singular of 'мога' (He/She can). Context tells you if it's 'He can' or 'It is possible'.
Yes, it is the closest equivalent to 'should' or 'ought to' in English when used for advice or probability.
No. While 'бих' is the 1st person conditional, the construction with 'трябвало' is impersonal, so it must remain 'би'.
