Here are some English verbs that end in -er. They are rather like the verbs that end in -ish, but more common. Not included are things like steamroller and sandpaper, which while allowing usage as verbs, are primarily nouns. Also things like reconsider have not been included if a subform (consider) is already on the list. Thanks to swloter@dstsystems.com for several additions.
