The word "seld" is an archaic adjective meaning "rarely occurring" or "seldom seen." Its spelling may seem odd as it lacks a vowel, but it actually follows the rules of Middle English, the language from which it originated. In IPA phonetic transcription, "seld" is pronounced /sɛld/, with the "e" pronounced as a short "eh" sound. While this word is not commonly used today, it can still be found in some literature and poetry from centuries past.
The word "seld" is derived from the Old English word "seldan", which means "seldom" or "rarely". The root of this word can be traced back to the Proto-Germanic word "seldana", which has the same meaning. Over time, "seldan" transformed into "seldom" in Modern English, while "seld" evolved as a contraction of "seldom". The word "seld" is primarily found in dialectical and archaic usage, particularly in northern English dialects and Scottish English.
