'lake, pool'(Modern English tarn)
Always derived from ON, no direct cognates of the n. represented by OIcel tjǫrn 'small lake, pool' survive outside of Scandinavia. Its ult. etymology is uncertain, but a connection with the PGmc st. v. *teran- (cp. OE teran 'tear', Go dis-tairan, OHG zeran, fir-zeran 'to cut off, finish, fight') is often suggested. The distribution of this n. in ME texts and place-names provides strong circumstantial evidence in favour of ON origin.
