Sentence structure

Words arranged in O-S-V order like this example below:

(Regular S-V-O)--- "The dog barked, the cat ran"

(O-S-V)--- "The barking the dog did; the running the cat did"

This is a good example as in this sentence you must join two separate clauses. Here is a simple example:

(Regular S-V-O)--- "He ate the food"

(O-S-V)--- "The food, he ate"

Take note of how the words move around- that's the key.
