Physically many cats are able to get pregnant as young as only six or seven months old. However, it is better and healthier for pregnancy to occur when they're a little older. Often younger cats are not good mothers; the maternal instinct seems to be better developed when they're one year or older.
Initially, all modern linguistics was historical in orientation. Even the study of modern dialects involved looking at their origins. Ferdinand de Saussure 's distinction between synchronic and diachronic linguistics is fundamental to the present day organization of the discipline.
Etymology (/ËÉt.ÉªËmÉl.É.dÊi/) is the study of the history of words, their origins, and how their form and meaning have changed over time. By extension, the term the etymology (of a word) means the origin of the particular word. For a language such as Greek with a long written history, etymologists make use of texts in these languages and texts about the languages to gather knowledge about how words were used during earlier periods of their history and when they entered the languages in question.
