"Tha mi a' snàmh ann an abhainn."

Translation: I am swimming in a river.

[William36729]

supposedly (MacAlpine & MackEnzie) abhainn is wrong & river should be abhuinn - is this a modern spelling?

Definitely abhainn is not wrong, you’ll find this wrong in practically all Gaelic dictionaries… abhuinn looks like a variant obsolete spelling though – in older texts, both Gaelic and Irish, you’ll find some variation between a and u written in unstressed positions (compare eg. the name Seumas or Seumus).
