event

something that happens; an event
Something that happens at a certain time or place.
Patrón de uso:
a [adjective] occurrence; an occurrence of [something]
Error frecuente:
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"*.
Sinónimos
event (Very general; does not carry the slightly formal tone that 'occurrence' can have.)
|
incident (Often suggests a specific, sometimes notable or problematic event.)
Antónimos
absence (Emphasizes that no event or happening took place.)

rate or frequency of something
How often something happens, especially in a certain place or group.
Patrón de uso:
the occurrence of [something] (in/among [group or place])
Error frecuente:
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.
Sinónimos
incidence (Common in medical and statistical writing when talking about how often something happens.)
|
frequency (More general and everyday; not limited to technical or scientific contexts.)
Antónimos
absence (Indicates that no cases or examples of the thing are found in the group or area.)

one appearance in data or text
One time that a word, symbol, or other item appears in a text or set of data.
Patrón de uso:
an occurrence of [word/symbol] in [text/data]
Error frecuente:
Learners may confuse this technical sense with the everyday idea of an "event." In computing or text analysis, "occurrence" means one appearance of an item, not a real-world event. In casual conversation, it is more natural to say "times" or "examples" instead.
Sinónimos
instance (Very close in meaning in computing and statistics; slightly broader and more general than "occurrence.")
|
appearance (Highlights that the item shows up or is visible, without the technical feel of "occurrence.")
Antónimos
omission (Suggests that the item does not appear where it might be expected.)
