Thank you to an eagle-eyed reader who has spotted a slight glitch with the imperfect tense of verbs such as peindre and craindre. The imperfect tense of these verbs takes the form peignais, craignais etc (with gn). A spurious extra n has slipped into the spellings produced by the system. This is being looked into, and a correction should be available within the next day or so.
Unfortunately the error affects conjugations given by both the French dictionary and the French verb tables sections of the site.
No other types verbs are thought to be affected.
