fasten
UK: ˈfɑːsən | US: ˈfæsən
vt. to attach or fix securely
vt. to close or tighten (e.g., a belt or button)
vi. to become fixed or attached
The word "fasten" originates from Old English fæstnian, derived from fæst (meaning "firm" or "fixed") + the verb-forming suffix -en. The root fast traces back to Proto-Germanic fastuz, conveying stability or tightness. Over time, fasten evolved to specifically denote the act of securing or attaching something firmly, reflecting its Germanic roots in physical steadfastness. The suffix -en is a common Germanic verb marker, turning adjectives or nouns into action verbs (e.g., "soften," "strengthen").
