When using "they lacked", ensure the subject is clearly defined and the missing element is specific to maintain clarity and impact. For example, instead of saying "they lacked", specify "they lacked essential resources".
Common error
Avoid stringing together multiple clauses using "they lacked" as it can create convoluted sentences. Break down complex ideas into simpler statements for better readability. Instead of "They lacked the funds, so they lacked the resources, and they lacked the ability to finish", try "They could not finish because they did not have sufficient funds or resources".
