Verbs ending in -en based on adjectives

There are a small number of verbs made from adjectives (or occasionally nouns based on adjectives) with -en added, meaning to make something more of that quality the adjective describes.
These verbs fall into certain categories:
  • Dimensions and shape - lengthen, shorten, straighten etc
  • Light and colour - brighten, darken, whiten etc
  • Density and composition - harden, soften, thicken etc
  • Others - freshen, ripen, sweeten etc
These are ergative verbs, which means they can be transitive or intransitive, and where the object of the transitive verb becomes the subject of the intransitive verb.
  • The hot summer ripened the fruit earlier than usual.
  • The fruit ripened in the sun.
For more on ergative verbs see my post - Ergative verbs? What on earth are they?
Here are three short exercises based on -en verbs

The verbs have been divided up at random; each exercise follows the same form - fill the gaps with an appropriate form of the verb. Careful! There are one or two -ing participles, at least one passive. There are also some common collocations, and in the third group, an idiom.

Or you can print normally and the answers will appear on a separate page (Page 3). The lesson is on Pages 1-2. I strongly recommend doing a Print Preview first. You might want to change your margins and you certainly won't want to print every page.
