Pro Tip
Use with time expressions
Pair 'occur frequently' with time expressions like 'in summer', 'at night', or 'during meetings' to specify when something happens often.
Gold Rule
Avoid redundancy
Do not use 'occur frequently' when 'often' or 'frequently' alone would suffice. For example, 'This error occurs frequently' is better than 'This error occurs very frequently'.
Word Origin
From Latin 'occurrere' (to run to meet, present itself) + 'frequens' (frequent, numerous). 'Occur' entered English in the 16th century, while 'frequently' derives from Latin 'frequentare' (to do often). Combined as a phrase in the 18th century.
Usage Notes
