 - en: A verb-forming suffix from Old English -nian, used to convert adjectives or nouns into verbs (e.g., "sharpen," "widen").
 
Etymology Origin:
The word evolved from the Old English concept of stretching (streccan) to the Middle English straight (aligned), combining with the productive suffix -en to form a verb. The logic reflects physical action (making straight) and metaphorical extension (clarifying or resolving).
