Expert writing Tips

Best practice

Use "at certain times" to specify that something occurs during particular moments or periods, rather than continuously or randomly. For instance, "The library is less crowded at certain times of the day."

Common error

Avoid using "at certain times" when you mean to say "sometimes" or "occasionally". "At certain times" implies a level of predictability or specificity that "sometimes" lacks. For example, instead of saying "The bus is late at certain times", consider "The bus is sometimes late" if the lateness isn't linked to specific hours or conditions.
