A shoehorn is a curved tool, usually made of metal, plastic, or wood, used to help slide the heel of the foot easily into a snug-fitting shoe without damaging the shoe's structure. It assists in putting on shoes by guiding the heel into place smoothly.
Figuratively, the verb "to shoehorn" means to force or squeeze something or someone into a space, situation, or schedule where it does not easily fit or belong. For example, shoehorning an event into a tight schedule or a plotline into a story where it feels unnatural. This usage extends to both literal and metaphorical contexts, such as forcing a number of people into a small space or forcing ideas or characters into a narrative.
In summary:
- Noun: A tool to help slide the foot into a shoe.
- Verb: To force something into a tight, insufficient space or time.
