Final answer:
A Freudian slip is a speech error caused by unconscious desires or urges. Although not very common, speech errors are more frequent in everyday language.
Step-by-step explanation:
A Freudian slip is a speech error that occurs when we unintentionally substitute one word for another. According to Freud, these slips of the tongue are actually the result of unconscious desires or urges.
For example, if someone accidentally says 'I love you' instead of 'I like you', it may indicate a deeper, unconscious attraction.
While Freudian slips may not be very common, speech errors, such as mispronunciations or misspellings, occur more frequently in everyday language.
