The suffix “-ach” appears in a variety of English words, often derived from Scottish Gaelic, Scots, or Irish. Examples include topographical terms like “loch” (lake) and “glen” (valley), as well as words like “broch” (an Iron Age drystone tower). These terms frequently retain cultural and historical significance, reflecting the languages and cultures from which they originate.
Preserving these terms maintains connections to specific regional identities and histories. Their continued usage enriches the English language, offering nuanced descriptions of landscape features and cultural concepts not easily replicated by other vocabulary. Understanding their etymologies provides valuable insight into the complex linguistic history of the British Isles.
