template
A pattern or guide you reuse to make similar things.
A template is a pattern or guide that you use over and over to create something new. Think of a stencil you might use in art class: you place it on paper, trace around it, and you've got a perfect shape without having to draw it freehand each time. That stencil is a template.
Templates save time and help maintain consistency. A business might use a letter template so every message has the same professional format and company logo at the top. Your teacher might give you an essay template showing where to put your introduction, body paragraphs, and conclusion. Architects use building templates to ensure every window in a new house is the same size and shape.
In computer programs, templates are everywhere. When you open a blank document in a word processor, you're starting with a template that already has margins, font, and spacing set up for you. Website templates provide the basic structure and design, so you just add your own words and pictures.
The key idea is reusability: a template is designed to be used again and again, with small changes each time. You're not starting from scratch every time you need to make something; you're filling in a proven pattern that already works.
