語源
英語の原文（Wiktionary）
From Late Middle English whilst, whilest, qwhilste (Northern England), quilest (Northwest Midlands) [and other forms], from whiles (“during the time that, while; only so long as; provided that; because, since; until”) + -t (excrescent suffix, perhaps due to a combination of -(e)s and the following word the, or influenced by the superlative suffix -est).
