Meaning & History
From Sardinian siddu "seal, brand", or the related siddai/re "to seal, to tighten", from which come the phrases 'siddai is dentis' "to grit one's teeth" and 'siddàu siast ingùnis' "may you be sealed there", the latter of which would have been affectionately said to a child that wouldn't stay still.
