What is the meaning of every now and again?

"Every now and again" means occasionally, sometimes, from time to time, or now and then. It describes something that happens infrequently but not rarely.

Here are some examples of how it's used:

* "I like to go for a walk every now and again." This means the speaker doesn't walk every day, but they do it sometimes.

* "My parents visit me every now and again." This implies the parents don't visit regularly, but they do come to see their child occasionally.

* "The train is usually on time, but every now and again it's delayed." This suggests that delays are infrequent but not completely unheard of.

Essentially, "every now and again" implies a pattern of sporadic occurrence, something that happens periodically but not consistently.
