2465: lamb & yean Sep 9, 2021

Old English had the word 'ēanian' (now 'yean') for 'to lamb' as a verb, but 'lamb' is an Old English word anyway too. This disparity comes from two different roots, but the verbal form is related to many Romantic or Slavic nouns like the Latin 'agnus' (lamb) or Serbo-Croatian ја̏гње (jȁgnje). 'Lamb' on the other hand is mostly related to modern Germanic cognates, and even the English 'elk'. These both come from different Proto-Indo-European roots that converged into the same meaning, and in some languages one became dominant. By the Middle Ages, 'lamb' won out in English.

2314: Cat=Dog, Lamb, and Goat?—Wanderwort Apr 17, 2021

The word for 'dog' in Latin is 'canis' (hence English's 'canine') but the word for 'puppy' is 'catulus'. This also led to its own derivative word in English: 'cat'. This gets stranger however, with more distant relation to the Russian око́т (okót) meaning 'lamb', and Old Irish 'cadla' for 'goat'. Others go on still to connect this to the Arabic قِطّ‎ (qiṭṭ) (i.e. 'cat) and other Semitic words to classify this root as a wanderwort across Indo-European, Uralic, and Semitic languages without one clear origin. The original idea seems to involve however young, often small animals, or sometimes more generally animal fertility.
