universal
Applying to everyone or everything, with no exceptions.
Universal means applying to everyone or everything, without exception. When a school announces a universal dress code, it means every single student must follow it, regardless of grade or class. When scientists discover a universal law of physics, like gravity, they mean it works the same way everywhere in the universe, on Earth and on distant planets billions of miles away.
Something universal doesn't leave anyone out. Universal healthcare means medical care available to all citizens. A universal remote control works with many different brands of televisions and devices. When we talk about universal human experiences, we mean things everyone can relate to, like feeling happy when someone remembers your birthday or sad when you lose something important.
Universal is stronger than “common” or “widespread,” indicating absolute applicability. A popular movie might be common, but a universal truth, like “people need food and water to survive,” applies absolutely to everyone. When teachers say reading is a universal skill, they mean it matters for every subject and every future path a student might take. The word captures that sense of completeness, of truly including everything or everyone without exceptions.
