Everyday and every day sound the same, but they do different jobs.
Everyday is an adjective. It describes a noun, and it usually means ordinary, usual, or used often. Put it before the noun it describes. Example: These are my everyday shoes.
Every day is a time phrase. It means each day. It tells you how often something happens. Example: I wear these shoes every day.
A quick way to check is to ask what the words are doing:
- If they describe a noun, use everyday.
- If they mean each day, use every day.
Compare these:
- She enjoys everyday tasks. Here, everyday describes tasks.
- She studies every day. Here, every day tells us when she studies.
Memory tip: if you can replace it with each day, write two words. If not, you probably need the one word adjective.
