Kinda. There are several other nouns declined like it, but they make a small group, so I guess you can call them irregular.
Thanks! And could you please show us the declination on an example (e.g. 'gaffel')?
Why is it wrong to say dine gafler? Thought you could say both dine gafler and gafler dine
"Dine gafler" is correct, but if you wish to put the noun first it needs to be "gaflene dine".
So, "gaffelene dine" is incorrect because the plural of gaffel is irregular? So, did we learn somewhere earlier that gaffel was irregular, or were we just supposed to know that...
It's either 'gaflene dine' (definite+possessive) or 'dine gafler' (possessive+indefinite)
