Further: e: dialectal version of "det", i.e. "it" öa, åa: adding an a on the end of a noun is a dialectal way of expressing "the 'ö'" and "the 'å'", respectively.

[CRConrad]

But the 'e' doesn't precede any of the forms 'åa' or 'öa', but only the indeterminate 'å' and 'ö'. The 'e' is definitely 'en', not 'det'.

[kzrdude]

Wouldn't "e" just be a contraction of "en" in this sentence? Is it "det" in the dialect?

[CRConrad]

No, you're right, it's "en": "...en å, och i ån är en ö". "Det" would be totally ungrammatical, dialect or no dialect.
