järelevaelvad

Could you please specify what sense of the term järelevaelvad you want the article to cover? In Estonian, the phrase could refer to different concepts depending on the field (for example, electrical engineering, hydraulics, or a linguistic/terminology context). Providing the intended meaning or a brief definition will help me write a concise, neutral wiki-style article under 300 words. If you’re open to it, I can also offer a general, disambiguated overview that covers the main possible interpretations.
