Futur mit „wäert“

English speakers reach for "will" to talk about the future. Luxembourgish usually does not need any future form: the present tense with a time word is the normal way to talk about plans.

• Ech komme muer. - I'll come tomorrow. / I'm coming tomorrow.
• Mir fueren am August op d'Mier. - We're going to the seaside in August.
• Nächst Woch fänkt d'Schueberfouer un. - The fair starts next week.

wäert + infinitive

There is a future with wäert and an infinitive at the end of the clause:

Its typical job is a prediction or a guess about the present, more than a plan: Et wäert muer reenen. - It'll probably rain tomorrow. Hie wäert doheem sinn. - He's probably at home. That second sentence is about now, not about the future, which surprises English speakers who equate wäert with "will".

Not wëllen

The false friend is wëllen: Ech wëll kommen is "I want to come". If you mean a simple future, say Ech komme muer.

Which one to use

For your own plans and arrangements, use the present with a time word. Use wäert when you are guessing or predicting: Dat wäert net laang daueren. - That won't take long.
