Svenska Akademiens ordböcker (svenska.se)
Three Swedish Academy dictionaries — SAOL, SO and SAOB — searched at once, free.
What it actually is
The authoritative free reference for Swedish: SAOL for the sanctioned spelling and inflection of current words, SO for full modern definitions and usage, and SAOB for deep historical treatment — all searchable together from one box. When you need to settle how a word is spelled, inflected or actually used, this is where Swedes look too. Completely free with no account. It is monolingual throughout, so pair it with Lexin or Folkets lexikon until your Swedish carries you.
