Common mistakes in sentence types

3 mistakes learners make with sentence types, each one named and explained.

All common mistakes

Count the clauses that could stand alone: one is simple, two joined as equals is compound, and one leaning on another is complex.

A complex sentence called compound

What it looks like

'Although she was tired, she kept studying' is chosen as compound.

Why it happens

It has two clauses, and two clauses is remembered as the test for compound.

A worked example

Question. Although she was tired, she kept studying.

A common answer. compound

The answer. complex

Why. Although she was tired cannot stand on its own, so the two parts are not equals.

Put the two side by side

I wanted to go out, but it was raining: both halves are sentences, compound.
Although it was raining, I went out: the first half is not, complex.

Two clauses is not enough. They have to be equals.

A participial opener mistaken for a clause

What it looks like

'Running through the park, she felt free' is chosen as compound.

Why it happens

It has two parts separated by a comma, and it opens with something that looks like a verb.

A worked example

Question. Running through the park, she felt free.

A common answer. compound

The answer. simple with an opening phrase

Why. Running through the park has no subject of its own, so it is a phrase and not a clause.

Put the two side by side

She ran through the park and she felt free: two clauses.
Running through the park, she felt free: one clause and a phrase.

A clause has its own subject. Without one it is only a phrase.

A simple sentence called compound

What it looks like

'The dog barked loudly' is chosen as a compound sentence.

Why it happens

It is a complete sentence with several words in it, and compound sounds like a description of length.

A worked example

Question. The dog barked loudly.

A common answer. compound

The answer. simple

Why. There is only one verb and one statement, however long the sentence runs.

Put the two side by side

The dog barked loudly: one clause, simple.
The dog barked and the cat ran: two clauses joined as equals, compound.

Count the parts that could be sentences on their own. Compound needs two.

WAJD spots these patterns in your child's answers and names the one behind their wrong answers, instead of just marking them wrong.
