Beginning again after a pause is ibtida', or resumption. A renewed breath does not by itself make a starting point suitable. The reader must consider how the opening word relates to the preceding context. If restarting after a negation, condition or dependent phrase changes the intended sense, a few earlier words may need to be repeated.
Suitable resumption: one that preserves both syntax and meaning.
Unsuitable resumption: one that isolates a fragment so that the listener understands a different claim.
As practice, compare two potential starting points within a verse and consider the resulting meaning. When every consonant is pronounced correctly yet the sentence linkage is damaged, the remedy is to restart appropriately. Correct recitation depends on meaningful sequencing as well as articulation.
