Dear teachers,

Please read the sentence:

The economic boom and recession is a periodical occurrence.

Could please explain if I can use "periodic" in this sentence?

Looking forward to hearing from you.
Thank you in advance.

I'm not a teacher and although I believe they may well be interchangeable, I would have used "periodic" in this instance, as I tend to use the term "periodical" only in the context of a magazine (a "periodical").

I am not a teacher, but I'd say ...

periodical refers to directories, journals, magazines, something that is released periodically.

periodic refers to, for example, calculation, it might be a sign, waves, outputs, voltage and so on.

Hope this helps

Hi jiang,

periodic (adj.)
  1. Having or marked by repeated cycles.
  2. Happening or appearing at regular intervals.
  3. Recurring or reappearing from time to time; intermittent.
  4. Characterized by periodic sentences.
In technical use, periodic means “at regular or predictable intervals,” as in the Periodic Table of the Elements. Often, however, periodic is used to mean “occasional, intermittent.

periodical (adj.)
  1. Periodic.
    1. Published at regular intervals of more than one day.
    2. Of or relating to a publication issued at such intervals.
n.
A publication issued at regular intervals of more than one day.

Dear Neillythere,

Thank you very much for your explanation. But in my dictionary 'periodical' can also be used as an adjective.

So what shall I do?
