A sentence needs controlled boundaries

1 · Learn

A main clause can stand independently. A subordinate clause depends on another clause, as in 'Although the path was flooded, we continued.' The opening clause creates a relationship but is incomplete on its own in ordinary formal prose.

A comma alone does not normally join two independent sentences. Use a full stop, a suitable conjunction or an appropriate semicolon. Fragments can be deliberate in creative writing, but their effect should be controlled.

2 · Worked example

I revise 'The bell rang, we left' to 'The bell rang, so we left' or 'The bell rang; we left.' The choice changes how explicitly the connection is stated.

3 · Your turn

Correct the comma splice in 'The rain stopped, the path remained flooded' while preserving the contrast.

4 · Apply your learning

Identify clauses in your own paragraph and revise one boundary for clearer meaning.
