Will Have Done: Bydda I Wedi

Level 4

Swap yn for wedi after bydda i, and you get "will have done": Bydda i wedi gorffen — I'll have finished.

How It Works

The pattern: bydda i / byddi di / bydd e, hi / byddwn ni / byddwch chi / byddan nhw + wedi + verb-noun

  • Bydda i wedi gorffen erbyn pump. — I'll have finished by five.
  • Byddwn ni wedi bwyta erbyn hynny. — We'll have eaten by then.

Questions and negatives soften, as in Fyddi di? / Fydda i ddim:

  • Fyddi di wedi gorffen erbyn dydd Gwener? — Will you have finished by Friday? Answer Bydda or Na fydda.
  • Fyddan nhw ddim wedi cyrraedd. — They won't have arrived.

A good guess. Just as in English, it can mean "has probably": Bydd hi wedi anghofio. — She'll have forgotten. For a firmer conclusion, see rhaid bod.

By when? Use erbyn + a time (erbyn pump), or erbyn i + subject + a soft-mutated verb-noun (erbyn i ni gyrraedd), as with ar ôl i and cyn i.

In speech, wedi is often shortened to 'di: Bydda i 'di gorffen.

Examples (5)

  1. Bydda i wedi gorffen erbyn pump.

    I'll have finished by five.

  2. Fyddan nhw ddim wedi cyrraedd eto.

    They won't have arrived yet.

  3. Erbyn i ti gyrraedd, bydd y plant wedi mynd i'r gwely.

    By the time you arrive, the children will have gone to bed.

  4. Fyddi di wedi gorffen erbyn dydd Gwener? Bydda.

    Will you have finished by Friday? Yes, I will.

  5. Paid â phoeni, bydd hi wedi anghofio.

    Don't worry, she'll have forgotten.

Common Mistakes

  • Mutating the verb-noun after wedi.

    Bydda i wedi orffen.
    Bydda i wedi gorffen.

    Wedi never causes mutation.

  • Putting ddim after wedi.

    Fydda i wedi ddim gorffen.
    Fydda i ddim wedi gorffen.

    Ddim comes straight after the subject, before wedi.
