present participle 
noun Grammar
The form of a verb, ending in -ing in English, which is used in forming continuous tenses, e.g. in I’m thinking, alone in non-finite clauses, e.g. in sitting here, I haven’t a care in the world, as a noun, e.g. in good thinking, and as an adjective, e.g. in running water.It is not surprising, therefore, that present participles can sometimes function as prepositions (concerning, considering, regarding are representative examples)....
- Each title begins with the words ‘The Bed, The Chair,’ followed by a description of a depicted activity, often expressed in present participles.
- French uses the present participle in its verbal form much less frequently than does English.
