datt

Etymology
From, from , north-western variant of , from. Cognate with 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

The split between and  is due to the fact that the latter is virtually never stressed, which prevented the otherwise regular lengthening (note that  may also be pronounced with a short vowel in unstressed position). The byform does not directly continue, but is actually from  + , thus from a contraction  →. Compare, etc., and compare for the contraction from underlying. The subsequent generalisation of, however, was surely reinforced by the form in Standard German and in dialects to the south-east of Luxembourg.

Conjunction

Usage notes
