Common mistake:
Learners sometimes say *"at this occurrence"* when they mean *"on this occasion"* or *"at this time"*. Use "occurrence" to name the event itself, not the time around it. Spelling is also difficult: it is "occurrence" (with double 'c' and double 'r'), not *"occurence"* or *"occurance"*.

Common mistake:
Learners sometimes use this technical meaning when they only need the simple word "times" or "how often". For example, instead of "the occurrence of rain was high," it is more natural in everyday speech to say "it rained a lot" or "it rained often." In scientific or formal writing, however, "occurrence" is appropriate.
Meaning
rate or frequency of something
Collocations
the occurrence of disease
|reduce the occurrence
|high occurrence

incidence (Common in medical and statistical writing when talking about how often something happens.)

Meaning
