The story

From Middle English terne, tarne (‘lake; pond, pool’), from Old Norse tjǫrn (‘a small lake without tributaries’), from Proto-Germanic *ternō (‘water hole’), perhaps related to *turnaz (‘bitter, embittered’), ultimately from Proto-Indo-European *der- (‘to separate, split; to crack, shatter’). The word is cognate with Danish tjern, Faroese tjørn (‘pond’), Icelandic tjörn (‘pond’), Norwegian Bokmål tjern (‘small forest or mountain lake’) (Norwegian Nynorsk tjern, tjørn), Swedish tjärn (‘small forest lake’).
