Frequently Asked Questions
Is 'mentido' irregular?
The past participle 'mentido' is actually regular—it follows the standard '-ido' pattern. However, the base verb, *mentir* (to lie), is irregular because its stem changes (e to ie, and e to i) in many tenses.
When does 'mentido' change its ending (mentida, mentidos)?
'Mentido' changes its ending only when it is acting as an adjective, describing a noun (like 'the false promise' or 'la promesa mentida'). When it is used to form a verb tense (like 'he mentido'), it never changes.
