constantly
Happening all the time or very, very often.
Constantly means happening all the time without stopping, or so frequently that it feels continuous. If your little brother is constantly asking questions, he barely pauses between “Why is the sky blue?” and “Where do clouds come from?” and “Can birds sleep while flying?” If it's constantly raining during your camping trip, the rain never really stops, turning your adventure into a soggy challenge.
The word describes something that repeats over and over with almost no breaks. A dripping faucet drips constantly. A mountain river flows constantly, day and night, year after year. Your heart beats constantly from the moment you're born.
Sometimes people use constantly as an exaggeration to emphasize how often something happens, even if it's not literally nonstop. When someone complains, “My phone is constantly buzzing with notifications,” they might mean it happens many times an hour rather than every single second. The word captures that feeling of something being relentless or unending, whether it's genuinely continuous or just feels that way. If you practice your piano scales constantly, you're dedicating serious, sustained effort to improvement, which is how skills get sharpened.
