BBC Materclass: Participle Clauses

A participle is a form of a verb - either ING or Past Participle (3rd form of a verb). A participle clause is a subordinate clause which begins with a participle. They usually show things like event order, time, cause and effect:
Stepping on camera, I relaxed completely. (When I stepped on camera)
Filmed inside, the footage was too dark to use. (Because it was filmed inside)

Beware the participle claws! Get it? Claws…like the nails of an animal. Clause…like the part of a sentence… no? Alright, look it doesn’t matter. This is everything you need to know about participle clauses. Stay tuned.
A participle is a form of a verb. A participle clause is a subordinate clause which begins with a participle. They act like adverbs and are linked to the main clause of a sentence. They usually show things like event order, time, cause and effect.
Stepping on camera, I relaxed completely.
or
Filmed inside, the footage was too dark to use.
There are present participles, ING, and there are past participles which are basically the third form of the verb. Stepping on camera…stepping is an example of a present participle. It basically means ‘When I stepped on camera’. Filmed inside…filmed is an example of a past participle. It basically means ‘Because it was filmed inside’. It is very important to remember that participle verbs do not change their form to show tense. This actually happens in the main clause, and participle clauses usually mimic the same tense as the main clause. However, it is possible to put a tense in a participle clause by itself. For example:
Knowing I was filming today, I wore a shirt.
Participle clauses often have implied subjects. This means that the subject of the participle clause is the same as the subject of the main clause and so it is omitted in the participle clause. For example:
Seeing the mistake, she corrected it immediately.
However, it is possible for a participle clause to have its own subject – and this is a little bit more formal. So, for example:
Seeing she had made the mistake, she corrected it immediately.
To make a participle clause negative, we use ‘not’, and this comes before the participle verb. So, for example:
Not knowing the baby slept, she phoned.
However, the ‘not’ can come after the participle verb depending on your meaning. So, for example:
Not knowing the baby slept, she phoned.
versus
Knowing not to call because the baby slept, she waited until the next day.
Got it?
To make clear that one action is finished before the action in the main clause is begun, we use Having + the past participle. And this basically works the same way as ‘because’ or ‘after’. So, compare:
Putting away the equipment, they talked about going home. – that means ‘while’
but
Having put away the equipment, they went home. – that means ‘after’
Finally, all sorts of prepositions can sit before the participle verb to further emphasise or clarify events’ order, time, cause and effect. Words like after, before, since, while and with. So for example:
By practising every day, she passed her driving test.
Without knowing it, I had ruined everything.
